Fix editor and project tests
Use rest caller in upload tests, fix breakages

There were a few errors regarding project and version creation.
Using the ZanataRestCaller removes these and reduces test runtime
by roughly 10 seconds where a project and version needs to be
created.
Also make the contact admin test less strict.
