HID will not work if STM32FreeRTOS.h is included.

env: Arduino 1.8.9 + Arduino_Core_STM32 + RobotDyn STM32 MINI
code:
```c++
// It does not work if there is this line.
// #include <STM32FreeRTOS.h>
#include "Keyboard.h"

void setup()
{
  Keyboard.begin();
  delay(1000);
  Keyboard.print("test");
  while (1);
}

void loop()
{
}
```
