Expense was meant to be sort of stateless (with the exception of isDeleted) to minimize risk of bugs but along the way became mutable.

Made isSettlement flag immutable
Actually tried to make involvedIds[] immutable but it turned out to be lot more involved (pun not intended) than I thought it would be so didn't do it.
