[IMP] core: do not log error for unmet dependencies on add_modules

When migrating a database, load_marked_modules will be called multiple times, alternating
to upgrade and to install modules. The main reason for this is still a litle confusing
but it as the side effect to log "Unmet dependencies" error multiple time in add_modules,
even if the dependency will be resolved later.

This commit removes the error level for this log, and replace it by another check,
performed at the end, logging any module in "to install"/"to upgrade" state.

Also log removed module as info (25), not warning. This may be changed latter

closes odoo/odoo#43797
