contributions of incorrect values created under some circumstances

Price fields of type 'Text' do not translate to the correct amount if the array has been iterated through already.

Presumable this only happens if a hook has touched them. The fault is the use of the key function which "key() returns the index element of the current array position. " which only works if the key is in the first index position.

Note I've seen incorrectly rendered prices sets on contact display as well - I think these are a separate (as yet unfound) instance of this or the problem pattern in CRM-14793 where PriceFieldIds & priceValueIds are transposed
