Comment 8 for bug 1510516

Test repositories need to have an Origin field so that it differentiates itself from others. This must be fixed so that the metadata "n=mos8.0,a=mos8.0,l=mos8.0" is different slightly enough so we can write a proper pref file.

Secondly, after this is fixed, we could add a check into nailgun that compares the metadata between configured repositories and looks for conflicts. This may be a large amount of work, however.
