Remove MergeRequest#target_branches and its usages
What does this MR do?
MergeRequestController#update_branches
controller action has been removed in 244f511e
Now we can remove the view as well @target_branches
instance variable and this variable was the only one which used MergeRequest#target_branches
The commit also removed the usage of MergeRequest#source_branches
. Since we don't use that method anymore, we can delete it as well
