Repo owner's PR's will not build unless skip_branch_with_pr is true

If the owner of a repository creates a branch, pushes it, and then creates a PR, appveyor will not build it because of the branches filter (which is currently main & release).  This used to work but i'm guessing appveyor made a breaking change and this stopped at some point.
