Resolves #427. Moves the module(s) reset operation to the stop() method

so that the modules are reset after they are shut down, in order to
prepare for processing chain reuse.

Previously, the modules were reset upon startup, but after any traffic
channel metadata had already been transferred to the channel state,
causing the metadata to be lost and allowing initial audio packets to
stream without any metadata and related streaming/monitoring rules.
