Fall back to project repository type by default

Closes #60007

See merge request gitlab-org/gitlab-ce!27003

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
