Remove calls to deprecated MessageLoop methods in suggestions_service_unittest.cc

Remove calls to deprecated MessageLoop methods in suggestions_service_unittest.cc

This CL replaces calls to MessageLoop::RunUntilIdle with
RunLoop().RunUntilIdle() in suggestions_service_unittest.cc.

Note that there is no reason to call RunUntilIdle() multiple times
in a row. After a call returns, the MessageLoop is idle. It stays idle
until a task is posted or a timer expires. There is no reason to call
RunUntilIdle() before that.
