refactor: handle undefined aniIconPath in DeviceListView

[52cyb]

1. Prevent crashes when model.aniIconPath is undefined
2. Add explicit check for undefined before checking the length
3. Set default empty string to avoid invalid source errors

Influence:

1. Test DeviceListView with audio devices that have no animation icon
2. Verify playback button visibility logic works correctly
3. Check that no console errors appear for missing icon paths

fix: 处理设备列表视图中 aniIconPath 可能为 undefined 的问题

1. 防止当 model.aniIconPath 未定义时导致程序崩溃
2. 在检查字符串长度前增加显式的 undefined 判断
3. 设置默认空字符串以避免无效的 source 错误

Influence:

1. 测试带有无动画图标的音频设备的设备列表视图
2. 验证播放按钮可见性逻辑正常工作
3. 检查无图标路径时是否出现控制台错误

PMS: TASK-392413

Hi @52cyb. Thanks for your PR.

I'm waiting for a linuxdeepin member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Reviewer's Guide

This PR hardens DeviceListView’s AnimatedImage binding against undefined aniIconPath values by defaulting the source to an empty string and tightening the visibility condition to explicitly guard against undefined before checking length.

Handle undefined aniIconPath in DeviceListView’s AnimatedImage to prevent crashes and invalid source errors.	Change the AnimatedImage source binding to fall back to an empty string when aniIconPath is falsy. Update the visibility expression to include an explicit aniIconPath !== undefined check before using its length. Keep existing play button visibility logic, now made safe for devices without animation icons.	src/plugin-sound/qml/DeviceListView.qml

Hey - I've left some high level feedback:

• The visible binding can be simplified to avoid explicit undefined checks by using a truthiness guard such as visible: showPlayBtn && model.aniIconPath && model.aniIconPath.length !== 0, which both prevents crashes and keeps the condition more idiomatic.
• Since source already normalizes aniIconPath to an empty string (model.aniIconPath || ""), you might reuse that logic for visibility (e.g. bind to a local property or use the same expression) to avoid duplicating and slightly diverging conditions for when the icon is considered present.

## Overall Comments
- The `visible` binding can be simplified to avoid explicit `undefined` checks by using a truthiness guard such as `visible: showPlayBtn && model.aniIconPath && model.aniIconPath.length !== 0`, which both prevents crashes and keeps the condition more idiomatic.
- Since `source` already normalizes `aniIconPath` to an empty string (`model.aniIconPath || ""`), you might reuse that logic for visibility (e.g. bind to a local property or use the same expression) to avoid duplicating and slightly diverging conditions for when the icon is considered present.
