tests: tolerate http2

You can run tests like this:
run-tests.py -l --extra-config-opt ui.usehttp2=true

And ideally, no tests should fail...

Tests for change/delete conflicts, including:
b5605d88dc27: Make ui.prompt repeat on "unrecognized response" again
 (issue897)

840e2b315c1f: Fix misleading error and prompts during update/merge
 (issue556)

Make sure HGMERGE doesn't interfere with the test
