tests: add test about aborting content-divergence when multiple parents

This patch adds tests for --abort flag of hg evolve command when we are
resolving content-divergence which are on different parents and parent of one of
them is the gca of both of them.

The tests shows that we are doing good and we should advertise the flag during
conflicts.
