Due to a bug in DeviceCommunicationService.isConnected(), devices using the
INITIALIZED state only worked when they had useAutoConnect set to true (Mi Band)
Now setting devices to INITIALIZED state to allow any action send to
DeviceCommunicationService is mandatory. As an exception only
REQUEST_VERSIONINFO will be also be allowed for CONNECTED state.
This also fixes a problem when notifications came in on the Pebble with 3.x
FW before we actually knew it was FW 3.x (INITZALIZED state on the Pebble
now implies that we know the FW version)
It's still very much possible to leak the descriptor (when an exception occurs
somewhere in between or anything else goes wrong). So maybe the whole thing
should be redesigned to be independent of files.
