If a `gasPrice` was specified in a transaction sent via a dapp, we would include it in our `eth_estimateGas` call, causing it to fail if the user had insufficient balance (for either the transaction amount or the gas fee). This resulted in the fallback gas estimate being used; the block gas limit. The block gas limit is quite a bit larger than most transactions need, so this resulted in wildly inflated gas costs being shown on our confirmation screen. The `gasPrice` has been removed from the `txParams` object we pass to `eth_estimateGas`, so now it won't perform any balance checks anymore. This ensures that we'll get a valid gas estimate, as long as geth is able to simulate the contract execution properly. Fixes #9967
