This function should take  GetEntryInfoWithFilePathCallback instead of
GetEntryInfoCallback so that the callers can get the drive file path.
The new signature matches GDataFileSystem::GetEntryInfoByResourceId()

Along the way, add CopyResultsFromGetEntryInfoWithFilePathCallback() to
gdata_test_util.h.
