Javascript files always loaded if a module is auto_install even when dependencies are unmet

[Guewen Baconnier @ Camptocamp]

Hi,

The web framework always loads the static files of modules (javascript etc) when the ``auto_install`` key is ``True``.
That's not accurate when the ``depends`` has some dependencies, the static files have to be loaded only if all the dependencies are satisfied.
That's the normal behavior, an ``auto_install`` module is only "auto installable" when all the dependencies are satisfied.

This issue has probably to do with Session.modules in controller/main.py [1]
