[PATCH] Omit sync package while mocking empty interface

when just an empty interface is has beeing mocked, the import of the sync package caused an error. In production it isn't important, because mocking empty interfaces might be stupid, but while writing tests it might happen, that you create an interface, which is beeing filled later on.
