If you close Mercurial repo branch, Bitbucket sends a webhook which contains push/changes/new section.
This misleads our CI (AppVeyor) integration and we start unnecessary builds.
I am not sure this is expected behavior because Git webhook does not work this way (branch deletion webhook does not contain push/changes/new section).
Can we rely on value of push/changes/closed? Should it be always false for all webhooks except branch close/deletion?
