Fixup of PR734: Coverage of hiredis.c (#1124)

Improve coverage (#734)

* Remove duplicate tests

- double covered by:
  "Can parse RESP3 doubles"
- bool covered via:
  "Can parse RESP3 bool"

* Make (connect) timeout in test config general

* Set error string in Unix connect with invalid timeout

Restructure testcase since redisConnectWithTimeout() and
redisConnectUnixWithTimeout() now behaves similar.

* Use quiet flag in lcov/genhtml instead of piping to /dev/null

* Fixup of redisCommandArgv test case

* Update test case to match what it covers

Use new test case info text since the previous one seemed copy&pasted.
The sought coverage was the handling of the parent-chaining
for a double object, which the test case now focuses on.
