Imported projects should be cloned from upstream

When loading projects from an external git repository a new project is created under "system" space having as origin this external git repository.

However, when one or more projects from this repository is/are imported, these projects are created as clones of the "system" repository.

The problem comes when hooks are needed to push changes to the remote repository (upstream)

The following approaches should help overcome this problem, depending on the complexity of each one:

• Clone directly from the remote repository (if the link to the "system" repository is no longer needed)
• Add an upstream remote pointing to the remote repository and keep the "origin" one pointing to the system repository
