autoproj 2.03: git submodule not reseted to correct commit id

[D-Alex]

If autoporj is used in combination with git submodules and tags the submodule is not properly updated to the correct commit id after the main git was rested to the given tag after checkout.

Workaround:
call: 'git submodule update' after checkout to sync submodule

Actually, it seems that submodules are only handled at checkout time.

Is running "git submodule update" after an update of the "master" repo the right workflow in all cases ?

[jakobs]

Maybe 'git submodule update --init' to catch the cases where new submodules have been added?

[doudou]

I'll add a test ... I really know nothing about submodules. They look like a pain.
