call-stream: fix endpoint and jingle transport states mapping

The function _endpoint_state_changed_cb() passes an enum TpStreamEndpointState between tp_call_stream_endpoint_get_state() and wocky_jingle_content_set_transport_state() without conversion, this last function expecting an enum WockyJingleTransportState, which is not completely equivalent.

typedef enum
{
    TP_STREAM_ENDPOINT_STATE_CONNECTING = 0,
    TP_STREAM_ENDPOINT_STATE_PROVISIONALLY_CONNECTED = 1,
    TP_STREAM_ENDPOINT_STATE_FULLY_CONNECTED = 2,
    TP_STREAM_ENDPOINT_STATE_EXHAUSTED_CANDIDATES = 3,
    TP_STREAM_ENDPOINT_STATE_FAILED = 4,
} TpStreamEndpointState;

typedef enum
{
  WOCKY_JINGLE_TRANSPORT_STATE_DISCONNECTED,
  WOCKY_JINGLE_TRANSPORT_STATE_CONNECTING,
  WOCKY_JINGLE_TRANSPORT_STATE_CONNECTED
} WockyJingleTransportState;


The visible consequence is that jingle considers that the connection is established (and the media stream can start flowing) when the endpoint state is /fully/ connected (value 3 for both enums), instead of /provisionally/ connected only. This may have a significant impact when the state provisionally connected is reached very early, and  the state fully connected takes much more time.
