Prevent crash

While not using the stumbler, a dialog would still pop up saying that the stumbler
had crashed:

E/AndroidRuntime(25424): Caused by: java.lang.NullPointerException
E/AndroidRuntime(25424):        at org.mozilla.mozstumbler.service.StumblerService.onStartCommand(StumblerService.java:138)
E/AndroidRuntime(25424):        at android.app.ActivityThread.handleServiceArgs(ActivityThread.java:2729)
E/AndroidRuntime(25424):        ... 10 more

This is annoying to users, so should be stopped.

Persist the "Upload only on wifi" preference
Always do as the user requested with respect to the Geofence Enabled switch

Previously, it would only turn off in a very specific circumstance.  After
this change, it should always set the geofence enabled to what the user selected.
