mod_bookmarks: Suppress error publishing empty legacy bookmarks w/ no PEP node

It appears that when:

1) The user has no bookmarks 2 node in PEP
2) The client publishes an empty bookmark set to a legacy bookmarks location
3) mod_bookmarks will attempt to purge items from the non-existent node and
   log an error about the failure (item-not-found).

This new code will suppress an item-not-found error from the purge operation
in the empty-bookmarks case, and adds a log message for any other error (this
is helpful because the existing log message confusingly says it was an error
*publishing* to the node, which isn't always accurate).
