Merge check does not work when using Branch Updater automatic branch merging on Bamboo

Steps to reproduce

1. Create a repository with a master branch and a feature branch
2. In Bamboo, create a plan connected to this repository
3. In Bamboo plan branch configuration, enable Branch Updater automatic merging with push on success enabled
4. Create a branch plan for feature branch
5. Make a commit to master
6. Make a commit to feature (non conflicting change)
7. Run the branch plan

Observation

Bamboo add a new commit to feature branch in Bitbucket Cloud. However this commit is never built as it was built before the push by Bamboo. Bamboo also ignores this commit when polling for changes.

This will cause merge checks with success builds to fail as the latest commit does not have a build. The only workaround would be to run the branch plan again manually so that the latest commit gets built.
