qt: Network-specific example address

Browse source 
Generate an (invalid) example address for in the bitcoin address
widgets, based on the network prefix, instead of hardcoding a mainnet
address.

- `1NS17iag9jJgTHD1VXjvLCEnZuQ3rJDE9L` for mainnet (same as now)
- `n2wxQmfexkjwEPgdD6iJA7T7RtzkmHxhFc` for testnet
