      In SERVER-78235 we added a rewrite for $count accumulator in a $group stage. However, we need to move the check if the collation matches to rewriteMinMaxGroupAccm(), since $count doesn't depend on the collation. This way even if the collation doesn't match we can rewrite a $group stage that has a $count accumulator.
