Description Felix Botner

Seems that the schema registration is triggered only once per app, even if the app is removed and re-installed.

install with failure during registration

* installation of app
* ldap schema registration
* ldap_extensions listener is triggerd, schema registation fails
* now, the app is removed from the appcenter, but not the schema 
  (which is good, we do not remove ldap schemas)

re-installation

* but as one tries to install the app again, the ldap schema registration 
  does not trigger the ldap_extensions listener (the ldap object for the
  schema already exists and is not changed in a way, that the listener
  handler is triggered)

Workaround, remove the settings/ldapschema object (but that is not the solution!)
