Problem/Motivation

Comment::hasParentComment() checks if there is a parent comment, and it does so by checking if it can load an entity.

That has two problems:
a) we might be loading the entity when we don't need it.
b) The default value for that field is 0, which then does a load(0), this is currently not being cached.

To reproduce:

Enable threaded comments, create a node with a bunch of comments without a parent.

Proposed resolution

If possible only check for ->target_id, or at least check that before checking ->entity.

Remaining tasks

User interface changes

API changes
