title: 'property' object is not callable
body: <p>So I have am connecting to a contract, and that seems to work fine, I am trying to use this class: web3.personal.Personal from <a href="https://web3py.readthedocs.io/en/stable/web3.personal.html" rel="nofollow noreferrer">https://web3py.readthedocs.io/en/stable/web3.personal.html</a> and I dont seem to understand what i am dong wrong...  when i print(web3.personal.Personal) gives me back a class object but I cant seem to use any functions associated with this class, says I am missing "self" argument</p>
  
  <pre><code>contract_abi = my_abi
  w3 = Web3(HTTPProvider(myurl))
  myContract = w3.eth.contract(address ,abi)
  ref = ref = web3.personal.Personal('web3')
  print(ref) #this works   
  print(ref.newAccount(password='the-passphrase')) #This crashes
  
  TypeError: newAccount() missing 1 required positional argument: 'self'
  TypeError: 'property' object is not callable
  </code></pre>
