Wallets generation with indexes more than 9

[6od9i]

What happened?

There is bug with generation wallets from seed when index has more than 1 symbol, for example:
address of wallet "m/44'/60'/0'/1" same with wallet "m/44'/60'/0'/10" or "m/44'/60'/0'/121"

What are the steps to reproduce?

• Run createNewCustomChildAccount from BIP32Keystore with pathes "m/44'/60'/0'/1", "m/44'/60'/0'/10" and "m/44'/60'/0'/121"
• Generate addresses for that wallets

1. It will be equal

What is the expected behavior?

Need generate diifferent thrue addresses

What is the error thrown?

Wrong addresses for index more than 9

What's the stack trace said?
