Git: main repository should be default when submodules are present (SSH remote)

[dahjelle]

Summary

When opening a repository (via SSH remote) with multiple submodules, the git panel picks one of the submodules (arbitrarily?) as the git the active git repository, instead of the top-level repository.

Description

Steps to trigger the problem:

1. Open a git repository with submodules via SSH remote.
2. Open the git panel.
3. Look at the active repository/branch selector.

Actual Behavior:

• A random(?) submodule is selected as the repository for the git panel to work with, instead of the top-level repository.

Expected Behavior:

• The top-level git repository should be selected by default.
• The repository picker should have submodules sorted alphabetically. :-)
