Just updated the Bitbucket Branch Source Plugin within a multibranch pipeline to the latest version, and it is full of welcome changes (thank you!). I'm using a webhook to send events to Jenkins from Bitbucket private instance. 

One thing that appears to be missing, is a feature that we commonly use in our workflow, which is to build `dev` or `master` whenever the PR is merged. So with this plugin, we have the following outcome

Branch Push -> Build

PR Open -> Build

PR Updated (via pushing code) -> Build

PR Merged into Dev -> *Dev NOT built (*I would like `dev` to be built here.)

I am seeing the hook in the pipeline events, but `dev` does not build unless I do a manual scan (or a timed scan, but that defeats the purpose of build triggers) 

Am I doing something wrong, or is this a feature request?
