साचा:License migration is redundant

Note: This साचा is used on a lot of pages. In order not to put too much load on the servers, edits should be kept to a bare minimum. Please discuss proposed changes on the talk page first.

Editing a साचा causes all pages that use the साचा to be re-rendered. If the साचा is used often, this can put a lot of load on the servers since it fills up the job queue.
Keep in mind that templates that are used on file description pages also show up on other wikis.

Returns redundant if one of the redundant templates is passed, otherwise nothing.
