tests: fix a test case to not create conflicts

This is the test case where we are testing about divergence resolution of stack
of patches. If the stack is as follows:

C1 C2
 | |
B1 B2
 | |
A1 A2
 \/
base

And A1-A2, B1-B2 and C1-C2 are content-divergent, and merging A1-A2 results in
conflicts.
Now if you resolve conflicts and continue resoling B1-B2, the conflicts of A1-A2
will still be there. We need somehow to understand the work we has done and not
create conflicts again.

To test the evolution functionality for now, we make sure conflicts does not
occur.

====================================
Testing head checking code: Case A-7
====================================

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 A: simple case involving a branch being superceeded by another.
TestCase 7: multi-changeset branch, split on multiple other, (head on its own branch), same number of head

.. old-state:
..
.. * 2 branch (1-changeset, and 2-changesets)
..
.. new-state:
..
.. * 1 new branch superceeding the head of the old-2-changesets-branch,
.. * 1 new changesets on the old-1-changeset-branch superceeding the base of the other
..
.. expected-result:
..
.. * push allowed
