Adjusted expectatios of verify_sdp.sh check. Instead of 'ALL CLEAN',
we now expect 'NO ERRORS' and an indication of 1 warning, due to the
addition of a check for a license file that does not exist. A missing
license file is considered a warning rather than an error.
The test suite doesn't exercise the new 'so many days left until your
license expires' check, but that can't be reliably tested without
a license file generator.
