Avoid crash when the activity is killed by the system in extremely low memory situations

This is a workaround, waiting for a real fix for the bug.
It should not happen if the GPS is running (foreground service with a sticky notification for the user)
Moreover, it can occur more likely on old devices with little RAM

Update Google Play Services
Update PebbleKit to SDK 2.0

It should work with both firmware 1.x and 2.x (tested with fw 1.13.0 and 2.0-beta2)
It allows to use 2.x firmware functions (such as getWatchFWVersion), if Exception are correctly catched on firmware 1.x
