tests: add a remaining test on evolving obsolete wdir parent

The obsolete parent was split in multiple successors. As one can see
after updating to the common obsolete parent it prints a message
suggesting to run `hg evolve` to update to its tipmost successor.

But, given suggestion doesn't work as expected and instead return error
saying parent is obsolete with multiple successor.

This will be fixed in upcoming patches.
