Fixes bug: pass wrong type parameters to jondis.pool.Pool.__init__()

Fixes error like this:

```python
Traceback (most recent call last):
  ...
  File "/.../jondis-0.1.10-py2.7.egg/jondis/pool.py", line 146, in get_connection
    timeout=self.timeout)
  File "/usr/local/lib/python2.7/Queue.py", line 172, in get
    endtime = _time() + timeout
TypeError: unsupported operand type(s) for +: 'float' and 'list'
```
