AddPayment uses the wrong amount.

[OskarOstlund]

When the store itself rounds currencies do the plugin use the original value, for instance would the store use one amount in SEK for an example 150 SEK, then convert it into DKK (109,88 DKK) and round that value to the closest value (110 DKK) should the checkout send the rounded value 110 DKK as the value used in the addPayment api call.

Currently in the example above would the value when the order were converted into DKK 109,88 be used and it would then include a seperate rounding of 0.12 KR as part of the entire addpayment calls rounding. This has some rather negative effects on our merchants as it can result in a rounding that exceeds the minimum amount of 0.5 SEK that skatteverket allows.
