The copy link button for forum posts should not include the ID of the user copying the link

If I click on the copy link button on a blockstack forum post, the link looks something like this.

https://forum.blockstack.org/t/how-would-something-like-a-forum-page-work-on-blockstack/5216/2?u=clydedcruz.id.blocks

Would be cleaner if it did not include the ID of the user who copies the link.

The format of the link is determined by our forum provider, Discourse.
