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.
