AcademicBenchmark: fix missing error message

There are several fatal errors that can be encountered in an import.
these were previously being reported as warnings, which is not accurate.
Additionally, the error message was not being set properly so in the
outcomes import API we were getting back a null error message.

Fixes CNVS-22517

Test Plan:

Most of these conditions are difficult to reproduce because they result
from the Academic Benchmarks server.  Therefore, there isn't really a
practical test plan we can do without building an emulator (which I
actually would like to do when we have a little time)
