Simplify logic for connect in MapClientProfile 

* connect: remove connected device check logic. MapClientService
  will check it.
* remove member variable V and related checks.
* wrap if/else statement in curly brackets.
* add robotest for MapClientProfile.

Bug: 111812003
Test: make -j42 RunSettingsLibRoboTests ROBOTEST_FILTER=MapClientProfileTest
