Fix for [GH-165] - createClient to properly assign parser_module
Add comma to package.json
Add failing test.

The test demonstrates failure for the following scenario. A single-subscription
client calls unsubscribe immediately followed by a subscribe. It will fail when
it tries to receive the next pmessage/message because the client will be in
false pub_sub_mode. Here is why it is false: First, the 2nd subscribe sets
pub_sub_mode to true during send_command. Next, the unsubscribe's
return_reply sets pub_sub_mode to false. The 2nd subscribe's return_reply does
not re-set pub_sub_mode back to true. So the result is a client with false
pub_sub_mode that fails upon receipt of the next message or pmessage.
Add fix for last test (re-establish pub_sub_mode = true)
