diff tests/test-graft-interrupted.t @ 44040:58db8f63f4e2

tests: split out ~1/3 of test-graft.t

test-graft.t is ~2400 lines and takes 34s to run. This patch moves the
last ~1/3 of it to a separate file. The parts now run in 22s + 13s. On
top of that, we can remove the #testcases from the old file, so it's
only 22s + 2*13s instead of the 2*34s it was before.
