Get pubsub numsub working

PUBSUB NUMSUB did not work

Expected Results

Command returns number of subscribers to list of channels.

Actual Results

Error. Two problems -

1. command needs to be in two parts - command and sub command.
2. the results need to be parsed in pairs - channel and count.

Steps to Reproduce

1. Run the test I've just written.

@PeterAdams-A Great catch I take it you ran into this in production? If so, I'm sorry for the bug!

changed milestone to %2.0.0

added bug releasepatch labels

@Mordil No - I didn't run into this in production. I've started looking at the namespacing idea (https://gitlab.com/Mordil/RediStack/-/issues/94) so commands which return Channels or Keys are interesting test cases.
