BUG: When "Find Sony Ci media... " button returns a 400, the "searching..." feedback does not go away.

[afred]

To Reproduce
Steps to reproduce the behavior:

1. Go to the Edit Asset interface for an Asset
2. In the "AAPB Admin Data" section, click the "Find Sony Ci media...."
3. Notice the feedback text displays the string: "searching..."
4. If the response results in a 400 Bad Request error (and maybe other errors), feedback text does not change, indicating that it's still searching. But it's now stuck and will always appear that way.

Expected behavior
If the call to Sony Ci Api results in any kind of error, then the feedback text should reflect that, maybe with a user-friendly message like "There was an error connecting to Sony Ci"
