CCPA support for SPA or refresh ad units

[ronzilca]

Type of issue

Feature (it's a bug, I think, but according to the code, it was planned this way).

Description

Within CCPA states, the default usprivacy string is 1YNN.
But, users can choose to opt-out and avoid using cookies. Then, the usprivacy string becomes 1YYN.

The problem is when I want to refresh ad units, according to the consentManagementUsp, the usprivacy won't update.

Steps to reproduce

1. Enable the usp consent module:

                pbjs.setConfig({
                    'consentManagement' : {
                        'usp'               : {
                            'cmpApi'                    : 'iab',
                            'timeout'                   : 100
                        }
                    }
                });

2. Change the usprivacy cookie (1YYN to opt-out).
3. Ask the __uspapi for the current status:
   __uspapi('getUSPData', 1, (a, b) => { console.log(a, b) });
4. Refresh the ad units

Expected results

The new bid request should contain the current usprivacy string.

Actual results

The new bid request contains the old usprivacy string.

According to issue #4425 it was not planned this way:

"Because the USP API does not wait for a user response, if it was not successfully obtained before the first auction, we should try again to retrieve privacy data before each subsequent auction."

and this indeed appears to be a bug to be fixed by removing the four lines at https://github.com/prebid/Prebid.js/blob/master/modules/consentManagementUsp.js#L161
