[HOLD for C+ manual payment] Rename CONST.IOU. MONEY_REQUEST_TYPE to CONST.IOU.TYPE

[tgolen]

Problem

This constant name isn't really correct. It does not hold the type of "money request" (which is manual/scan/distance), but instead it holds the type of IOU (which is split/request/send).

Why is this important?

It creates confusion in the code

Solution

Rename the const to CONST.IOU.TYPE
