bitbake: runqueue: Fix errors when using -S printdiff

When running printdiff, messages like:

"Can't find a task we're supposed to have written out?"

might be shown. This happens when hashequivalence is enabled and is due
to the use of "hash" when "unihash" should be used (which defaults back
to hash). Changing this fixed various errors oe-selftest highlighted.

Also print the task ID when erroring about a missing task as it aids
debugging.
