Commit 413952ff944d10164d9d08a8a48e7725fe44b1b3

Authored by Sebastian Ziebell
1 parent 566de5ab
Exists in master and in 4 other branches 6-8-stable, 7-0-stable, 7-0-stable-spb, spb-stable

Creating or updating a MR returns more informative status codes. 

Using the API library to create or update a merge request at the moment a 404 error is returned.
This is fine when the merge request in question does not exist, but does not provide good
information that for example a required attribute is missing.
A status code of 400 (Bad request) is returned when creating or updating a merge request
when either `source_branch` or `target_branch` is missing. A status code of 409 is returned
when `source_branch` and `target_branch` are the same. Tests are added for these cases.
