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.

====================================
Testing head checking code: Case B-1
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category B: simple case involving pruned changesets
TestCase 1: single pruned changeset
