Setup rules for when to display/ not display folder labels.

Allows us to pre-display label changes on the ui side.
Rules are as follows:
1) if the current folder and the folder added on the conv are the same,
don't show the folder in the converation item
2) if the current folder is a system folder and the folder added on the conv
is also a system folder and they are of the same type, don't display it
(covers priority inbox and inbox)
