Shortcut to create MR in web IDE57482-shortcut-to-create-merge-request-from-web-ide

Before the user had to choose between committing to a new branch,
committing to a new branch AND creating an MR, or committing to the
current branch regardless of whether or not it already has an MR.

This commit separates the creation of an MR from whether or not they
commit to an existing or new branch
