XEP-0198: fix race conditions on enable/resume

This code splits out the `enabled` property into `enabled_in` and
`enabled_out` to reflect that client and server enable 0198
asynchronously.

This also moves the actual enabling code into the stanza processing
logic, because apparently, `enable.send()` was just added into the end
of the send queue, but `enable` got enabled immediately, so that poezio
requested ACKs for whatever happened to be in the queue before.

Async is hard, let's go get fishing.
