bookmarks: correctly update current bookmarks on rebase (issue2277)

When you rebased with a currently active bookmark, that bookmark would
always point at the new tip, regardless of what revision it pointed at
before the rebase.

All bookmarks will now point at the equivalent post-rebase commit.
However, the currently active bookmark will cease to be active unless
it points at the new tip post-rebase.  Rebase will always leave the
new tip as the working copy parent, which is incompatible with having
an active bookmark that points at some other revision.  The common
case should be that the active bookmark will point at the new tip
post-rebase.
