  Incorrect return value example for web3.personal.newAccount
  http://web3py.readthedocs.io/en/stable/web3.personal.html?highlight=newAccount#web3.personal.newAccount
  
  The documentation provides the following example:
  
  ```
  >>> web3.personal.newAccount('the-passphrase')
  ['0xd3cda913deb6f67967b99d67acdfa1712c293601']
  ```
  
  However, the return value is the address as a string, not an array containing it:
  
  ```
  >>> web3.personal.newAccount('the-passphrase')
  '0xd3cda913deb6f67967b99d67acdfa1712c293601'
  ```
