Empty state for "There is nothing to merge from source branch into target branch."
Issue idea came from: https://gitlab.com/gitlab-org/gitlab-ce/issues/28558#note_25125088
Usecase
With the new `Create merge request button from https://gitlab.com/gitlab-org/gitlab-ce/issues/28558#note_25125088 people will be redirected to a merge request view with nothing in there to merge.
Problem
There is no clear way for a user to act upon a merge request view with nothing to merge.
This should improve slightly upon one of the states in https://gitlab.com/gitlab-org/gitlab-ce/issues/25424
Design
Improve empty state on merge request widget by showing the user a way to begin creating content
- CLI option
- new file gui option
- nice drawing

Value
