tests: move verification closer to setup in test-copies-chain-merge.t I found this test case really hard to read because it requires scrolling back and forth between the setup and the verification. This patch moves them closer together. There was also duplicated descriptions for each test case (duplicated between setup and verification). They had already become out of sync. I picked the description from the verification, partly so the differences would be highlighted in this patch. Differential Revision: https://phab.mercurial-scm.org/D8377
