Whenever any character is added to an empty advanced search string the app crashes.

Steps to reproduce

2. Open a music folder
3. Type !artist="" in the search input
4. Type any character inside the ""

Alternative steps to reproduce

1. Open Tagger
2. Open a music folder
3. Type !artist=" in the search input
4. Type a search term after "
5. Add " after the search term
6. The app should filter correctly until this point
7. Position the cursor after the last character of the search term, before the closing "
8. Tap the Backspace key a few times

Expected results
