No need to copy the list when we queue deletions

It was a shallow copy to begin with, which resulted in said index out of
bounds exceptions, so now that we added queuing it's no longer needed to
copy the always-2-field dict.
Don't add 'action' field to new entries anymore

I thought I removed this but I didn't.
