Since v14 (with commit[1]), we prevented users from creating 'link.tracker'
and 'link.tracker.click' records.

This is not ideal because creation of the link trackers should be allowed
whenever needed (for example to add it in a button somewhere, ...) unlike
'link.tracker.click', which is a technical model and so the records should
always be created by system.

This commit partially reverts commit[1] and allows users to create the
'link.tracker' records if user is having enough access rights.
