0.0.12: Fix seq_no persisting across sessions (#33)

* Fix seq_no persisting across sessions

When using an instance of the client to run multiple sessions (calling
.run multiple times), the seq_no of the subsequent sessions didn't start
with a zero. Now it does, so we send the same messages regardless of
using single or multiple client instances to run multiple sessions.
