Merge branch 'search-filters-label-fix' into 'master'

Fixed search dropdown labels not displaying

## What does this MR do?

Returns the search controller method after finding the project & group.

## Why was this MR needed?

The search controller was returning early when the search term was empty causing a bug where the dropdown toggles wouldn't show the correct text - instead defaulting to `Any`.

## Screenshots (if relevant)
