fix broken healthcheck tests

Four of the healthcheck tests were completely broken. They
were written with the option '--healthcheck-cmd' which is
not an option (it should be  '--healthcheck-command', with
'command' as a full word). The tests were merely checking
exit code, not error message, so of course they failed.
I have fixed the command line and added checks for the
expected diagnostic.

(Side note: do not write tests that check exit code but
nothing else. This should not need to be said).

One of the four tests was invalid: --healthcheck-interval 0.5s.
Per Brent:

   initially i was going to restrict sub one-second intervals

That test has been removed. It would probably be a good idea
for a future PR to add some validation such as preventing
negative values, but that's left as an exercise for later.

Also: grammar fix in an error message.

Caught by my ginkgo log greasemonkey script, which
highlights 'Error' messages and grabbed my attention.
