Currently, 030 just compares the error class, which does not say
anything.

Before HEAD^ added throttling to test_overlapping_4, that test actually
usually failed because node2 was already gone, not because it was the
commit and stream job were not allowed to overlap.

Prevent such problems in the future by comparing the error description
instead.
