ztest: Update verification to account for missing suite
ztest: Update verification to account for missing suite

Fix an issue where a test's suite name was misspelled and thus the
test never ran because it wasn't associated with a suite. Example:

ZTEST_SUITE(my_suite, NULL, NULL, NULL, NULL, NULL);
ZTEST(myy_suite, test)
{
}

The above will no longer pass since `myy_suite` with a double `y` will
fail the verification.
