content-div: add test showing `--stop` works during interrupted resolution

This patch adds a test showing that the --stop flag of `hg evolve` works well
during interrupted content-divergence resolution.

The --stop flag now works with all the three different type of instability
resolution very well and we should advertise it more.

+Tests for the --stop flag for `hg evolve` command while resolving content-divergence
+==================================================================================
+
+The `--stop` flag stops the interrupted evolution and delete the state file so
+user can do other things and comeback and do evolution later on
+
+This is testing cases when `hg evolve` command is doing content-divergence resolution.
