pkg/covermerger: we don't need branch info

The first versions of this code used branches for git checkout.
Later the git repos were merged and branch info usage was reduced.
The latest changes switched the code from branch checkout to commit checkout.
There is no need in branch info anymore and I don't see any use-cases for it.
