           Summary: enumerateDevices() doesn't return correct list of
                    devices after device was changed by user in a system
                    preferences

Steps to reproduce:

1. Have two or more available microphones
2. Call getUserMedia and then enumerateDevices: 
browser will return a list of devices, where first one is default
2. Change microphone is system preference
3. Call enumerateDevices again:
first one in the list is a previous default device


Js fiddler to show the issue: https://jsfiddle.net/h38bn7zq/15/


Note: if device is unplugged then enumerateDevices returns correct info, it works correct also when device was plugged in after.
