There's a loss of information when hex encoding and passing to eth light wallet (chain id is lost). This results in a different signature. While it may work on testnets it is not sufficient for our test cases. We can export the private key and use it in our PrivateKeyWalletSubprovider
Added assertions on addresses for public methods
Throw a helpful error message when signer address is not instantiated address in PrivateKeyWalletSubprovider
Update changelog and rename derivationBasePath to baseDerivationPath
When returning undefined use pattern of IfExists
Added configuration object for MnemonicWallet
Put constants back into each individual wallet rather than in walletUtils
Delete accidental package-lock.json
