Bitbucket Server 7.0 PR fetch from not working

[Michael Kriese]

I have updated a PR (push) and our ci is trying to fetch the commit with 

`git fetch origin +refs/pull-requests/575/from:refs/remotes/origin/PR-575`

But the fetch gets the old ref. So it looks like the ref is no longer updated since bitbucket 7.0.0.

Using `git fetch origin renovate/jint-3.0.x` to fetch the source branch works.

We are facing the problem with the latest Bitbucket v7.4.0.

Our CI system can not find remote references of our pull requests.

$ git fetch origin refs/pull-requests/34/from:
fatal: Couldn't find remote ref refs/pull-requests/34/from

Bitbucket app also shows an error:

Object "refs/pull-requests/34/from" does not exist in repository 'My Repo'

Here the issue
