wallet: use minimum mixin when RPC asks for too low mixin

After the fork, normal transfer functions called via RPC
use the minimum mixin 2 if 0 or 1 is requested. While the
incoming transaction may be valid (eg, it has an unmixable
and at most a mixable input), it is a simple way to make
sure RPC users can't get a seemingly random accept/reject
behavior if they don't update their requested mixin.
