Expose expire_date when enforced

[tobiasKaminsky]

As admin

• sharing -> set default expiry after 2 days
• enforce it
• share a file a.txt via link

Get http://localhost/nc14/ocs/v2.php/apps/files_sharing/api/v1/shares
with path pointing to a.txt and see

<expiration/>

There should be the date, so that clients can display it.
If it is enforced, it will be shown, but not editable in client.

Closing.
This was somekind of race condition. I enabled the setting, so old links are not affected, but newer are showing the date.
