tests: prepare fixing test-server CI workflows

the TAG variables handling was messed up between the workflow file and the test
script(s), causing the test-server CI checks to fail.
This change prepares fixing the test runs from the worflow file by
stopping the server image test script from wrongly rewriting
the LOCAL_TAG variable
