Load fundamental apps, before any possible customizing app may follow

ac7fb1b2 brought a regression that fundamental apps are not loaded anymore in some circumstances.

Examples:
- LDAP user logs in, but cannot use text editor
- LDAP user logs in first time, First Time Wizard does not show up
(both described in https://github.com/owncloud/core/issues/8963#issuecomment-46088834)

My fix is just to load the fundamental app types – authentication, then filesystem and logging –  before anything else (as it properly happens in other places, i guess it was just overseen).

Then my friend your problem is unrelated to the PR.

Because, all apps are loaded at this point anyway. The only change here is that some specific app types are loaded earlier.
