tests: add test of resolution of content-divergent stacks

This patch adds a test of resolution of content-divergence stacks where a series
of changesets get mutated as two different series resulting in whole
content-divergent stacks.

As the tests shows, we are not processing the changesets in right order which
needs to be fixed first.
