Fix media view not being refreshed when selecting a different media folder

[daniele-verducci]

How to reproduce:

• Open app
• Go to media view
• 3 dots menu -> select "Set media folder"
• Choose another media folder
• The view is not refreshed*

• = this may not happen the first time, as the check is successful if there have been changes in the media folder. If you can't reproduce, retry.

@alperozturk96 I'm not sure this is the correct solution, can you take a look? I saw you worked on the same files previously.
The problem is that currently the check to decide if refresh the view is done on the return value of parseMedia(), but that one, as far as I can understand, refreshes the local files based on the remote ones and returnes true only if there have been changes. The result is placed in an emptySearch variable, so maybe it's just a misunderstanding. I think emptySearch must be true only if there are no files at all. Is it correct?
(note that the media view doesn't have a search feature, so the search is always called with an empty query)

blue-Light-Screenshot test failed, but no output was generated. Maybe a preliminary stage failed.
