Gestures don't work when turning on Explore by Touch pragmatically.

1. There was a misspelled duplicate member in the accessibility service
   class which was causing inconsistent behavior because one field was
   updated and another checked.

2. When the set of services that can put the device in explore by touch
   mode changes we were disconnecting and reconnecting all services
   and this is not correct. Now only the state of explore by touch is
   updated appropriately.
