4235 prebid endpoint return empty array instead of 204 when no bids returned (prebid#3136)

* corrected user sync type

* add alias pxyz
add version to endpoint
add validation for 204 bid response

* add validation with serverResponse is undefined
fix test for 204 (no bid response)

* remove package lock

* restore package-lock
