MSC2312 self-message results into error "No permission"

[krille-chan]

Description

When I try to click a matrix: link onto my own account, I receive error "No permission".

To Reproduce

1. Send a link to your account in style [DM me](matrix:u/mikaela:feneas.org?action=chat) (replacing the MXID with yours) in a room.
2. Click it
3. Answer the "Message user YOURMXID` with "Ok"
4. See error "No permission"

Expected behaviour: I get an error that I don't have a need to create a direct chat with myself or an empty room or something, I didn't expect "No permission".

Additional information:

• Device: iPhone SE2020
• OS and OS version: iOS 14.7.1
• Installed version of FluffyChat: 0.37.0

I formatted the link as per https://github.com/matrix-org/matrix-doc/blob/master/proposals/2312-matrix-uri.md
