heptapod-ci: make Windows jobs manual again

The dance continues, we make the Windows tests optional once again since we
don't have Windows runners available anymore. We're working on getting new ones
in a more stable fashion, hopefully soon.

Bookmark is usually an indication of a head. For changes that are introduced by
an ancestor of bookmark B, after moving B to B-NEW, the changes are ideally
still introduced by an ancestor of changeset on B-NEW. In the below case,
"BOOK-D", and "BOOK-E" include changes introduced by "C".

Previously, there was a bug where the empty commit check compared the parent
branch name with the wdir branch name instead of the actual branch name (which
should stay unchanged if --keepbranches is passed), and erroneously assumed
that an otherwise empty changeset should be created because of the incorrectly
assumed branch name change.
