Add min_fee before estimating predicates

[hal3e]

When estimating predicates we set the gas_price to 0 because we have no coins to cover for the min_fee. We should first estimate the min_fee add coins to cover it and then estimate Predicates and add new coins if necessary. Relevant code:

 fn estimate_predicates(
      &mut self,
      consensus_parameters: &ConsensusParameters,
      gas_costs: &GasCosts,
  ) -> Result<()> {
      let gas_price = *self.tx.gas_price();
      let gas_limit = *self.tx.gas_limit();
      *self.tx.gas_price_mut() = 0;
      *self.tx.gas_limit_mut() = consensus_parameters.max_gas_per_tx;

      self.tx
          .estimate_predicates(consensus_parameters, gas_costs)?;
      *self.tx.gas_price_mut() = gas_price;
      *self.tx.gas_limit_mut() = gas_limit;

      Ok(())
  }
