getAppPath can return false

Check if request is sent from official ownCloud client

Fixes https://github.com/owncloud/core/issues/23533

There are authentication backends such as Shibboleth that do send no Basic Auth credentials for DAV requests. This means that the ownCloud DAV backend would consider these requests coming from an untrusted source and require higher levels of security checks. (e.g. a CSRF check)

While an elegant solution would rely on authenticating via token (so that one can properly ensure that the request came indeed from a trusted client) this is a okay'ish workaround for this problem until we have something more reliable in the authentication code.

Makes code analyzers happier

This was used when we did not have lazy shares yet. Now that we no
longer support legacy shares this can go.

In 9.0 we converted the old shares to the new shares. So for 9.1 we can
savely remove the fallback code.

This code was required when there was no initiator set.

* Fixed unit tests

Allow OCP classes to be PSR-4 as well
