revset: fix commonancestor test so it demonstrates correct behavior

The problem is that hg log -r 'head()' is every changeset in the
repository, because in this test repository, every changeset has a
different branch. The author probably assumed all commits were on the
default branch, and that they were getting topological heads, 7 and 9.

As a result, this test was showing that the common ancestors of
0:9 are 0+1+2+4, which is not correct (next commit will test this).
