Bug#14286343: MAIN.STATUS TEST FAILS SPORADICALLY WITH RESULT CONTENT MISMATCH ON PB2

Issue:
------
The test case "Ensure that SHOW STATUS only changes global status variables"
expectation itself is wrong. Executing any query, including SHOW STATUS,
WILL change the statistics of the server, and this WILL change the result
of some status variables, global or per session. Expecting this behavior is
un realistic, and trying to observe it in a test case is bound to fail.

Fix:
----
Remove the test case "Ensure that SHOW STATUS only changes global status variables"
