Subject: [PATCH 1/2] fix(transform): use scheme as domain for file:// and
 other non-web URLs

When splitting URLs, file://, about:, and other URLs without a host
produced an empty string for $domain. This caused all such events to
cluster together as a single empty entry in "Top Browser Domains".

Now falls back to using the URL scheme (e.g. "file", "about") as the
domain when host is None. Matches the corresponding fix in aw-core
(ActivityWatch/aw-core#129).

Fixes ActivityWatch/aw-core#67
