Consul :: Add tests to cover health check path being used when heartbeat is off

[cieciurm]

Description

Hi all,

This PR fixes an issue when health check path is not respected when heartbeat is enabled.

This is a very simple attempt to fix the issue, by moving the short circuiting statement couple of lines lower.
Please let me know if it's too simple ;)
I've added unit tests to cover the issue scenario.

As a bonus, I've added a unit test to assert an exception being thrown when the specified port is a negative number.

If the solution is approved, then I can submit a similar fix for the v4 version (targeting main branch)

Fixes #1062
