Submit Language to pebble don't works

[cemoi71]

Hello,

seems that the language submit function to the pebble don't works. I tried to change the language into the French, then into the German one, and nothing happens. It still use the US one then. Furthermore, if we use the submit button for the first time after a rockpool restart, then it seems to block itself, and it is not possible to select the language and use the button any more (until restart). Observed with SFOS v2.0.5.6.

I find Rockpool is a cool app, i'm really surprised on how far it is functional developed. Amazing! Great job! to all contributors. Many thanks for this. Cheers
