fix(files_sharing): Sort by correct share attribute ("share with displayname")

There is no `title` attribute, so this causes an exception.
Instead sort by the "share with" displayname which will be the user or group the node is shared to.
Meaning this will also be the title of the share in the UI.
If this is not available or there are multiple for the same, then sort by the custom label.
If also this is not set sort by the creation time.
