fix interactive documentation examples for personal namespace

[eshaben]

The following problems exist within the personal namespace of the interactive docs:

• personal_newAccount example isn't working
• personal_unlockAccount example doesn't work because it relies on personal_newAccount
• personal_sendTransaction example doesn't work because it relies on personal_newAccount

The problem is due to the crypto-browserify package not being completely compatible with nodes crypto module. In personal_newAccount, encrypt is called and then we begin to run into errors with scrypt.

Could try setting up our own provider (like ganache.provider) and passing in own accounts. Or could try to polyfill the functions we need from the crypto package. Maybe try installing an scrypt browser-capable version, or using subtle crypto to .encrypt and .decrypt which uses the right aes type and so we could probably make it work somehow.

• JavaScript implementation of scrypt
• A WebCrypto Polyfill for NodeJS - This is not suitable for production and shouldn't be used but is relevant to the issue
