[TopGit PATCH] Use the topological order when exporting explicitly listed branches.

["martin f. krafft" <madduck@debian.org>]

From: Niko Tyni <ntyni@debian.org>

When exporting explicitly listed branches (tg export -b), the branch
dependencies were not taken into account.

Arguably, lines 178:189 need to be refactored due to the code duplication, but
the patch does what it should for now.
