Install the mongodb-odm for the static analysis

The composer config fakes the availability of ext-mongodb during the
dependency resolution (affecting only the case where FOSUserBundle is
the root package) as we don't need to be able to actually execute the
ODM to be able to do static analysis. This allows to avoid requiring
ext-mongodb for contributors.
