Uncommenting currently failing assertions due to reverting the changes done to RingBufferN.

This is done so we can deliver a quick fix with regards to arduino/ArduinoCore-samd#580 .

The real issue is a race condition somewhere within ArduinoCore-samd which we first need to identify, then those tests can be re-enabled again.
