Fix updating merge_when_build_succeeds via merge API endpoint

Browse source 
When updating a merge request via the `/merge` endpoint we
check the `mergeable` and `mergeable_state` status, these will return
`false` if the application option only_allow_merge_if_pipeline_succeeds is
enabled. We should skip CI checks if the request uses the
merge_when_pipeline_succeeds param

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/22740
