Reto Brunner 1687e558d3 notmuch/maildir: remove double emit of the dirinfo
There was some bug which could be worked around by double emitting an event.
However that proofed to be brittle:

We send the first message here from the worker goroutine:
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/maildir/worker.g=
o#L306

Then Tick() is waked in the main goroutine and calls ProcessMessage:
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/widgets/account.go#L100

ProcessMessage in the main goroutine reads types.Message state with
msg.getId() and msg.InResponseTo():
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/types/worker.go#=
L74-76

Meanwhile in the worker goroutine we call PostMessage for a second
time with a pointer that points to the *same* previous message that
ProcessMessage is reading:
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/maildir/worker.g=
o#L306

The second PostMessage call makes writes to message while
ProcessMessage in the main goroutine is possibly reading:
https://git.sr.ht/~sircmpwn/aerc/tree/a5553438/item/worker/types/worker.go#=
L59

This led to a data race in the event loop
