drop capital letter recognition

since one of the recent versions, FindMyDevice command became capital letter sensitive. this results in confusion, since it's not covered in wiki properly – for instance https://gitlab.com/Nulide/findmydevice/-/wikis/FMD%20locate describes capital FMD, while in app settings, the text to trigger fmd command is always decapitalized automatically. to actually trigger the command, in sms, it has to be written in lowercase letters. few versions ago it didn't matter. this is a request to drop capital letter recognition.
