When downloading a folder called "0001" PHP should fallback to parsing
it as string and properly detect that it is not a JSON array.
Use the cached fileinfo to get creatable permissions
Unset the cached active user when using a different session object
Close session when loading apps

Otherwise the session is blocked while all remote apps are loaded. This can be very annoying especially when apps.owncloud.com is down or not reachable.

Retrieve storage numeric id earlier when still available

The numeric id is only available before the storage entry is deleted, so
get it at that time.
Add unit test
Allow specifying protocol in ext storage OC config

Allow specifying a protocol in the host field when mounting another
ownCloud instance. Note that this was already possible with the WebDAV
config but this bug made it inconsistent.
