[Toaster] [PATCH] toaster: models Remove manual transaction control from lsupdates

[Michael Wood]

Revert "toaster: models.py do not use transactions".
This reverts commit e248a503ba84658dea086e65e9cde8b845b9c0ed
(Bitbake rev: 48d0d510816346073f135bb86fb7904fdb50bb27)

Manually manging the database transactions caused more
problems than it temporarily solved so we return control back to
Django's orm.
