Subject: [PATCH] don't use exact property for device ID

Use ideal property instead of exact property when calling getUserMedia API.
Since enumerateDevices API does not request device permission, the test page will not receive any device ID if camera permission is not already set nor will it trigger a device permission popup. Since getUserMedia API will be called with empty device ID using 'exact' property, test page will not display any video.
