Moved into a utility call. I will remove this method in subsequent PRs and use the utility directly.

We will have to resolve branches earlier.

This PR aligns handling of branches in reads and writes.
After this PR, we will allow writes that explicitly provide the branch to succeed even if WAP is configured. Just like we allow this for reads. If the user configures a branch via identifier or in option, it must override everything else. The only remaining difference is that writes are allowed to create new branches.
