how to clean salesforce_push_queue table from element with mapped_object_id = 0

Problem/Motivation

Hello,

I've noticed some lines in my salesforce_push_queue table with errors related to mapped_object_id = 0.

I couldn't find any Drush command to clear them out on demand.

I came across this comment in the code:

I find this comment :

    // Failed items will remain in queue, but not be released. They'll be
    // retried only when the current lease expires.
    // doCreateItem() doubles as "save" function.

Is it possible to propose a command to clean these up? Is there a reason why such a command hasn't been suggested?
