Even if the initial request line wasn't found. With the fix to 1455, the
test number is now detected correctly.
(Problem found when running tests in random order.)

Subject: [PATCH 4/6] sws: as last resort, get test number from server cmd file
If it can't be found in the request. Also support --cmdfile to set it to
a custom file name.
runtests.pl always writes this file with the test number in it since a
while back.
