bookmark: complexity pull-push test to have deeper tree
This changeset only touch test.
The previous test was correct, it tested that the successors of an old bookmark
position was seen as a valid destination for bookmark.
However, a newer version is made for two reason:
(1) The new test check further. It check that the descendant of the successors
is a valid destination
(2) An ever more complexe test is needed to validate a future fix to issue 3680
Splitting complexification of the test and actual bugfix help to reduce the
noise in the bugfix changeset. Issue 3680 is NOT fixed by this changeset.
