Log:
ScoPDetection: Obtain a known free diagnostic ID

... instead of hardcoding something that has been free at some point. This fixes
a crash triggered by r265084, where the diagnostic IDs have been shifted in a
way that resulted our hardcode ID to not be assigned any implementation.  Our ID
was likely already wrong earlier on, but this time we really crashed nicely.
