Fix some bootstrap issues

- fix recursive call of Base._aq_dynamic
- revert r39457 ("__of__ has no reason to trigger portal_type loading.")
- avoid problematic and useless interaction/reindexation
  while migrating a portal type

Steps to reproduce were:
0. make sure your browser is already logged (Manager may be required)
1. runUnitTest --save --portal_id=erp5 testBusinessTemplate
2. runUnitTest --load
3. open /erp5/portal_templates/view

Note: some errors were random.
