bookmark: informs of failure to upgrade a bookmark

When we explicitly requested to update a bookmark but the bookmark location was
missing locally, we used to silently ignore the case. We now issue a message
about it to point that something wrong is going on.

By chance, we fixed all the cases where is case happened (for explicit pulling
only, issue4700 is still open). But I think it is still valuable to have a
warning in place in case such issue is reintroduced.

This patch have been tested against issue4689 test (but without issue4689 fix).
It give the better but expected failure seen below:
