Fix T99997: Calling teleport without waiting for the previous event disables gravity

During teleport event, gravity is disabled and WalkMethod
is stored in `teleport.navigation_mode` which is used later to reset
the status after execution. Calling teleport events consecutively
will change the initial WalkMethod value. So update it only on the
first call. Also remove `else condition` as it stops the previously running
teleport when the new teleport call fails to find a hit point.
