wallet: Determine IsFromMe by checking for TXOs of inputs 

Instead of checking whether the total amount of inputs known by the
wallet is greater than 0, we should be checking for whether the input is
known by the wallet. This enables us to determine whether a transaction
spends an of output with an amount of 0, which is necessary for marking
0-value dust outputs as spent.
