[LLDB] Fix missing return value in SBBreakpointLocation::GetQueueName()

- Fix a typo in the function that never returns a significant value

- Add unit tests for the getters/setters in SBBreakpointLocation

- Verified the newly added unit test succeeds after the fix:
llvm-lit -sv  lldb/test/API/functionalities/breakpoint/breakpoint_locations/TestBreakpointLocations.py
