Some way to clean up a shortcut for an invitation that is no longer useable #3
Description
With io.picolabs.did-o and the dido library, invitations are currently single-use. Once the invitation has actually been used, we no longer need or ought to maintain a shortcut for it.
The didcomm-v2.out-of-band ruleset ought to at least allow for a manual removal of a shortcut.
Ideally, this should happen automatically, when the invitation has been used.
