[IMP] test_module_operations: make uninstall step more graceful

- process modules to uninstall individually in order to better handle
  their state at that point
- uninstall (and reinstall) modules in provided order, rather than
  whatever postgres feels like (or a sort which might not match what
  we want), mostly useful when uninstalling modules in bulk
- warn if a module is either missing or already uninstalled, rather
  than silently do nothing

closes odoo/odoo#120261
