Make sure that the encrypted version is set

fix creation of versions of encrypted files on external storages

This property can be queries by the clients so they know the max
permissions they can use to share a file with. This will improve the UX.

The oc:permissions proptery is not enough since mountpoints have
different permissions (delete + move by default).

By making it a new property the clients can just request it. On older
servers it will just return a 404 for that property (and thus they know
they have to fall back to their hacky work arounds). But if the property
is returned the client can show proper info.

Add setId and setProviderId to IShare interface

in order to create a 1:1 copy of a file if a version gets created
we need to store this information on copyBetweenStorage(). This
allows us to by-pass the encryption wrapper if we read the source file.
