title: Unable to unlock account with Parity and Web3 on the testnet
body: <p>I'm running a local Parity node for the testnet (Ropsten) on Debian (Jessie). I'm using web3.py to connect to this node and create transactions.</p>
  <p>I've created a new account:</p>
  <pre><code>parity account new --chain ropsten
  </code></pre>
  <p>I'm running my parity node with the following options</p>
  <pre><code>/usr/bin/parity --chain ropsten --no-ui --rpcapi 'eth,web3,personal' --jsonrpc-interface 127.0.0.1 --bootnodes 'enode://20c9ad97c081d63397d7b685a412227a40e23c8bdc6688c6f37e97cfbc22d2b4d1db1510d8f61e6a8866ad7f0e17c02b14182d37ea7c3c8b9c2683aeb6b733a1@52.169.14.227:30303,enode://6ce05930c72abc632c58e2e4324f7c7ea478cec0ed4fa2528982cf34483094e9cbc9216e7aa349691242576d552a2a56aaeae426c5303ded677ce455ba1acd9d@13.84.180.240:30303'
  </code></pre>
  <p>When I test this node, it's running fine, see the following python shell:</p>
  <pre><code>Python 3.4.2 (default, Oct  8 2014, 10:45:20) 
  [GCC 4.9.1] on linux
  Type &quot;help&quot;, &quot;copyright&quot;, &quot;credits&quot; or &quot;license&quot; for more information.
  &gt;&gt;&gt; from web3 import Web3, KeepAliveRPCProvider, IPCProvider
  &gt;&gt;&gt; web3 = Web3(KeepAliveRPCProvider(host='localhost', port='8545'))
  &gt;&gt;&gt; web3.eth.blockNumber
  1012932
  </code></pre>
  <p>However, when I try to unlock my account it returns False (with a proper account hash and password ofcourse)</p>
  <pre><code>&gt;&gt;&gt; web3.personal.unlockAccount('my-account-hash', 'some-password')
  False
  </code></pre>
  <p>When I check if it's actually in my list of accounts, I get the following empty array:</p>
  <pre><code>&gt;&gt;&gt; web3.personal.listAccounts
  []
  </code></pre>
  <p>However, when I check in parity:</p>
  <pre><code>parity account list --chain ropsten
  </code></pre>
  <p>It lists 3 accounts. Why is it not showing in the listAccounts? Do I have to make the account available somehow?</p>
