Pebble: no longer clear list of cached apps as soon as the installed watchfaces is received from Firmware 2.x

This will result in duplicate entries (first the whole cache, then actually installed watchfaces)
It might already make watchface configuation working on 2.x even though it is dirty

I wish everybody would just update to 3.x *sigh*
