fix: fix migrations on empty repositories

(#150)

Current implementation did it in wrong way. First of all, there was a
lookup through pkgbase instead of pkgname, which lead to errors, because
aur api doesn't allow to search by pkgbase (as well as provides is
basically pkgname instead)

It also was found that dependencies resolution lookup has been performed
by using raw packages array, which can include versions, descriptions
etc
