[Bug/Error] Can't use backspace to delete last three seconds of recording with multiple microphones

[AndrewDant]

Currently if you are recording with multiple microphones and hit backspace to delete the last three seconds of recording the following error is generated and the recording stops.
`----------- ERROR DURING RECORDING --------------

Traceback (most recent call last):
File "C:\Users\andrew.dant\Documents\Github\parrot.py\lib\record_data.py", line 328, in record_consumer
record_controls( key_poller, recordQueue )
File "C:\Users\andrew.dant\Documents\Github\parrot.py\lib\record_data.py", line 66, in record_controls
secondary_states[index - 1] = secondary_states[index - 1].get_detection_state()
AttributeError: 'DetectionState' object has no attribute 'get_detection_state'`

I tried to reproduce with a single microphone and could not, but I'm consistently able to reproduce with two microphones on Windows 10.
