Don't calculate tx fees for PSBTs with invalid money values

Browse Source 
In decodepsbt if an invalid amount is seen, don't calculate the fee
but still show the invalid value in the decode.

In analyze psbt, if an invalid amount is seen, set the next step to
be the creator as the creator needs to remake the transaction so that
it is valid.
