Comment (by spacedmonkey):

 @peterwilsoncc Not sure what you mean here. The goal of this change.

 If the term id is not a list of id to prime in cache, do not bother to
 prime them. If you load a single term meta for one id that is not in the
 queue to prime, then it may load data is very uses.

 Take the following example.

 {{{#!php
 get_term_meta( 999999 );
 }}}

 If 999999, you may load other term meta for now reason. See attached
 screenshots.

 Another solution to this problem, is dynamically adding the missing id to
 the queue, but again, this may result in loading data that is not needed.
