Fall back to project repository type by default

What does this MR do?

This makes sure that we always have a repository type when trying to parse a repository from a path.

This is needed because sometimes we want to perform access checks as if the project already existed, for example when creating a project on push.

Before this we were only doing that when accessing git over http, this makes sure it also works correctly when accessing git over SSH
