Fixing users walking infinitely

Now, if no event is received from the Pusher after MAX_EXTRAPOLATION_TIME, the
moving variable of the user is set to false.

So if a client does not send an update on time (for instance if the user switched
tab while walking), on the screen of others, the woka will appear to stop.
