Entering no fuzzy search ratio for Plex crashes the applet

[SolveSoul]

When trying to sync from Spotify to Plex the applet crashes when no fuzzy search ratio is set. Of course one should set-up a fuzzy search ratio but it shouldn't be possible to not enter a value or should default to another value when none is set by the user.

See details below:

@XDGFX +1 to this. I have the same issue on a docker install.
