parsers: fix two leaks in index_ancestors

Both happy paths through this function leaked the returned list:

1) If the list was of size 0 or 1, it was retained an extra time and then
   returned.

2) If the list was passed to find_deepest, it was never released before
   exiting this function.

Both paths spotted by cpychecker.

  $ hg init
  $ echo a > a
  $ hg add a
  $ hg commit -m test

Do we ever miss a sub-second change?:

  $ for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do
  >     hg co -qC 0
  >     echo b > a
  >     hg st
  > done
