Editing a note that doesn't match an active search causes note to be deselected

[dstillman]

1. Enter a search term.
2. Select a book (for example) satisfying the search term, which has an existing note.
3. In the right-hand panel, select a note, click on it and edit the note "in place" (not in a separate window). If the note does not contain the search term, it will disappear, leaving the message "no items selected" in the right-hand panel.

(In [1015]) Fixes #421, Editing a note that doesn't match an active search causes note to be deselected

If an edit causes a note to stop matching the quicksearch, clear the search

Also:

• Select text in quicksearch when using shortcut key instead of just focusing
• Fixed strict warning
