Is the context pointer the same when context->msgstate is ENCRYPTED and
when it's PLAINTEXT?  OTRL_MSGEVENT_ENCRYPTION_REQUIRED will only be
called when the msgstate is already PLAINTEXT, so the question is why
either (a) the context is switching to PLAINTEXT, or (b) a new context
is being created.  If you were using OTRv3, I would suspect it has to do
with instance tags and child contexts, but it appears you're just using
OTRv2?
