Removing and pushing to branch with existing MR makes it out of changes
Created by: qfox
How to reproduce:
- Push something to a branch 
test - Create MR for branch 
test git push origin :testgit push origin test- Open MR again
 
After rebasing branch, we removing it and pushing again. It makes existing MR empty.
It still contains old commits but Changes tab shows 0 changes.
How to force gitlab to refresh branch? Probably branch removes should trigger branch cache drop or something else?
