Track Progress link instead of View Details

Via https://github.com/Tendrl/specifications/pull/256 there should be `View Details` link when cluster is imported for tracking the import task, but in current version there's `Track Progress` link instead.

Tested with:
```
tendrl-ui-1.5.5-20180207T051807.2334615
```
