Scenario 1: The build merge check says "If there are more builds than specified above, they are all required to be successful in order to merge the pull request." however it actually blocks merges to wait for in-progress builds. Either the messaging should be updated to make this clear or the implementation should be updated to ignore in-progress builds.

Scenario 2: When we have configured the minimum number of required builds to a value like 1 0r more, the UI says, "You cannot merge this pull request while it has cancelled builds. You still need a minimum of 1 successful build before this pull request can be merged." when one of the recent builds is cancelled and blocks the user from merging the pull requests.
