ReadReceipt errors after migrating to as_token authentication

[baltitenger]

Since I upgraded the bridge and migrating my configuration to use the as_token appservice authentication method for double puppeting, I often see the following errors in the log:

Note that I logged out of the old sessions of the bridge from my matrix account, not sure if it's related.
