Removed TestServiceManagerContext from FileManagerPathUtilTests

Removed TestServiceManagerContext from
ExtractMountNameFileSystemNameFullPath and
ConvertFileSystemURLToPathInsideCrostini since they don't require it.

TestServiceManagerContext is causing flakes for
ExtractMountNameFileSystemNameFullPath.  The network thread that it
spawns is putting work on the queue just as TestBrowserThreadBundle is
closing down and violating checks.
