tests: reduce dependence on previous tests for setup

The tests in test-evolve-phase-divergence.t built on each other for no
good reason, which makes the tests hard to modify and hard to read.

This patch cleans up some of them. We should clean up the rest too,
but the rest won't matter for my next patch, so I haven't bothered.

This test file test the #6028 issue

evolve fails with mercurial.error.ProgrammingError: unsupported changeid '' of type <type 'str'>
