get sources for packages in multiple releases again

In 321213f0dcdcdaab04e01663e7a047b261400c9c Andreas Cadhalpun corrected
the incorrect overriding of earlier better-fitting results with later
(semi-)matches – but that broke the case in which packages are in multiple
releases in the same version (and the user has both releases configured).

Closes: 812497
