Pinning and unpinning a message leads to confusing text in the timeline

[davidegirardi]

Steps to reproduce

You need two accounts with access to a shared room.

1. MXID1 opens the room
2. MXID2 opens a different room or closes the client
3. MXID1 pins a message in the room
4. MXID1 un-pins the same message. They will see "MXID1 changed the pinned messages for the room."
   
5. MXID2 opens the room and sees "MXID1 pinned a message to this room. See all pinned messages." instead
   

Outcome

What did you expect?

Everybody sees "MXID1 changed the pinned messages for the room."

What happened instead?

MXID2 opens the room and sees "MXID1 pinned a message to this room. See all pinned messages."
