Update tests for rabbitmqctl version parsing

[wyardley]

Pull Request (PR) description

• Update existing tests to include the leading spaces and some additional formatting
• Add new test case for the newer format included in rabbitmqctl -q status that's included in RabbitMQ >= v3.8.x, originally fixed in Extend version regex for RabbitMQ 3.8 #814

See discussion in #872

That said, based on this, I believe the version parsing logic should function with >=3.8.x

This Pull Request (PR) fixes the following issues

note - I don't think the format has changed here between 3.1 and 3.7; just thought it was maybe a good idea to make the string a little more realistic (though it's still not multiline).
