test: verify order of error in h2 server stream

Currently the order of error / closing of an h2 stream is consistent
in 10.x, 11.x, and master. There appears to be an unexpected behavior
difference in 8.x. This test will be used to bisect the commit that will
fix this behavior change and ensure there are no future regressions.
