fix: Pass the mountpoint target user to storages without owner
Browse files Browse the repository at this point in the history
Storages that do not have a dedicated owner (e.g. groupfolders, external
storages) currently always assume the current session user as the owner.
This leads to several issues when there is no user session but a node is
obtained through a user folder.

In order to have the correct user available we need to pass the user
that is used to setup a mountpoint along to the storage layer as we
generally assume that an owner is available for those.
