BUG: 1) Controller processed twice in flight.py and 2) wrong if condition for sensor measurement

[zuorenchen]

Describe the bug

1. v1.12.0 refactors sensor and controller into __process_sensors_and_controllers_at_current_node. However, the controllers are processed once more in __simulate.

2. The if condition for sensor measurement should check if the sensor exists in the time_node instead of flight.sensor

Expected behavior

1. Remove duplicate
2. Use node._component_sensor to trigger sensor measurement
