enable delivery receipts in unencrypted rooms
This reverts commit a4595b427d22d4483d6add31b3f2e4816f2dbd1d.
Commit a4595b4 avoids sending delivery receipts to rooms that do not contain the bridge bot. That was necessary as trying to send a read marker would automatically attempt to join the bridge bot to the room. That join without invite would fail, hence #483.
But since https://github.com/mautrix/python/commit/f272f16a1d151a1c6612c9349776eda985c8ea3e we no longer attempt to join the sender of read receipts, fixing #483 without necessarily sacrificing the delivery receipt functionality.
See also mautrix-signal, which provides delivery receipts without the check removed in this commit.
Thus:
- a4595b4 is no longer necessary, its original purpose is fulfilled by f272f16.
- a4595b4 prevents delivery receipts from working in unencrypted rooms.
- This reverts a4595b4, thus enabling delivery receipts in unencrypted rooms.
Please note that I have not tested these changes on a live instance.
I have tested this on a live instance and as far as I can tell, things seem to work.
