[fix for 132] Two GetAssetOutboundFee patches #check-lint-warning
Two small fixes for the recent GasManager updates:
- Return GetFee instead of zero for GetAssetOutboundFee v131 (!3519 (comment 1880232775)) - this ensures a fee is still returned when the network is upgrading from 131->132
- Don't return error if no NetworkFee has consensus on a chain (!3519 (comment 1882036480)) - this maintains current functionality
