Fixes fail test cases in AccessibilitySettingsTest 

AccessibilityHearingAidPreferenceController can't be instantiated
correctly in tests with the lack of LocalBluetoothManager. This causes
null pointer exception when
AccessibilityHearingAidPreferenceController.setFragmentManager() is
called in AccessibilitySettings.onAttach().

Solution: Mocks the LocalBluetoothManager for tests to successfully
instantiate AccessibilityHearingAidPreferenceController to prevent null
pointer exception from happening.
