TwiML not generating correctly with <Client></Client> tags.

[phalt]

When using this code:

r = Response()
    with r.dial(callerId=caller_id) as r:
        r.client('admin')
    return r.toxml()

The output is:

u'<?xml version="1.0" encoding="UTF-8"?><Dial callerId="XXXXXXXXXXX"><Client>admin</Client></Dial>'

The <Response> tags are missing!

Further to this, I've discovered that this code generates the XML perfectly fine:

r.dial(callerId='+XXXXXXXXXXX').client('test')

Output:

>>> r.toxml()
u'<?xml version="1.0" encoding="UTF-8"?><Response><Dial callerId="+447943511601"><Client>test</Client></Dial></Response>'

Documentation describes the previous methods for generating TwiML.

I believe the with statement does not work correctly with the dial tag. Investigation is needed to see if this is a bug across all methods and not just dial.
