[fix][#33833] Incorrect message on "publish" exception. Fixes #3736

In case of ANY exception during "publish" the same error message was being displayed. The JLIB_DATABASE_ERROR_ANCESTOR_NODES_LOWER_STATE message is also irrelevant most of the times, like in non-nested tables.
Changed to show actual message string from the Exception object in catch argument.

Removing language string JLIB_DATABASE_ERROR_ANCESTOR_NODES_LOWER_STATE as this patch removes its only usage.
