[fix][test] Fix query server unit tests to check for status code

[mahadzaryab1]

Which problem is this PR solving?

• Resolves [Bug]: query: TLS handshake error #6230

Description of the changes

• We had a bug report come in [Bug]: query: TLS handshake error #6230 which wasn't caught by our unit tests. The reason here was because the test was not checking the status code of the response received from the server but rather just the error returned from doing Client.Do.
• • This PR also cleans up the tests to remove the manual dial call and an unnecessary filter in the test body.

How was this change tested?

• This test passes on main because of the patch that was landed in [fix][query] Fix misconfiguration in TLS settings from using OTEL HTTP helper #6239.
• To verify that this test would have caught the bug, I ran this test on the v1.63.0 release. Running this test caused failures in the following tests, all of which were returning 400 instead of 200.
