There's no way to undo a repost

[xaberue]

Description

In the main feeds view, after clicking on repost, (that it's currently just reposting without allowing quotes), at least for an MVP should allow to undo the repost by clicking it again.

Current behaviour

Having a post already reposted by the logged user, if clicking again, nothing happens.

Expected behaviour

Having a post already reposted by the logged user, if clicking again, undo the repost.
