Message tests check the output of a test against an expected file.
Executing with --stress-opt changes the output, since the test will be
run multiple times. For that reason, most message tests explicitly add
the --no-stress-opt flag.
Since this is redundant, and not a per-test setting, just configure this
globally for all message tests instead.
