The update routine tries to test the database migration before actually performing the update.
However, this will fail hard if the schema has changed (for example an unique key has been added). App developers can convert the DB in preupdate.php, however it is not called before and therefore the update fails.
This actually breaks ownCloud updates from ownCloud 6 to ownCloud 7 when the files_antivirus app is enabled.
The script required by require_once might use variable names like $app
which will conflict with the code that follows.
This fix encapsulates require_once into its own function to avoid such
issues.

Since getEnabledApps() depends on an authentication app to be loaded,
especially in the case of LDAP, the cache from getEnabledApps() is now
cleared to make sure that subsequent calls will properly return apps
that were enabled for groups.
This is because getEnabledApps() uses the inGroups() function from the
group manager provided by LDAP or any other authentication app.
Fix issue where the currently logged user was causing side-effects when
upgrading.
Now setting incognito mode (no user) on update to make sure the whole
apps list is taken into account with getEnabledApps() or isEnabled().
On SQLite the app order can be arbitrary and cause strange bugs.
On MySQL, the app order seems to be always alphabetical.
This fix enforces alphabetical order to make sure that all environments
behave the same and to reduce bugs related to app loading order.
