Database creation fails when there are auto_update, non installable modules

[Jerther]

By doing this:

• Odoo 10 (I believe this would also happen in earlier versions, but in this branch, project_timesheet_analytic_partner is auto_install and not installable which is needed for this issue)
• Map this repository as an addon path in odoo config:
  https://github.com/OCA/project.git
• Have erppeek create a database, then install module project_closing.

Actual result:
An Odoo error:

20170531 16:21:48.275 : FAIL : Pending actions:
  to install	project_timesheet_analytic_partner

This module is marked auto_install and not installable in its manifest file.

Expected result:
erppeek does not care about modules that are not needed by project_closing, and installs it.

Additional details:

• If I manually create a new database via the web interface, the project_timesheet_analytic_partner is pending, but I can still successfully install project_closing.
• I first thought Odoo was wrongfully trying to install those modules, but it turns out they're skipped, and it's a desired behavior.
• Then I turned to OCA, and asked them about modules being auto_install, and they said it was intentional because these modules are "glue" modules.
• I tried various things in erppeek.py in the _upgrade() method (around the "Safety check" comments) and I was planning on making a PR with some fix, but nothing worked and I eventually gave up.

Not sure how to handle this case.
As a workaround, you can set the state of the culprit module:

pending_install = model('ir.module.module').browse(['state = to install'])
print(pending_install.name)

# Then force the state
pending_install.write({'state': 'uninstalled'})
