Merge to target branch for validation

When validating a patch-set, we need to verify that the result
of a potential merge would work and NOT the single commit in isolation.

By validating the reuslt of the merge of a patch-set with its target
branch we get a much accurate feedback for deciding if it is safe
or not to merge a change.
