Fixed version of #163
My understanding is that the bid manager wants to see addBidResponse called the same number of times as expectedBidsCount, before executing the callback. Sovrn adapter doesn't set expectedBidsCount, so it will be set to the default (from adaptermanager.js):
Multiple Sovrn bid requests are merged into a single call to sovrn. When sovrn encounters an error or doesn't bid on anything, they don't sent an explicit no-bid response for each bid request. Before this PR change, the sovrn adapter called addBidResponse only 1 time in this case.
Thus addBidResponse may only be called 1 time. But bidmanager expects it to be called more times, so it does not fire the callback immediately, instead, it waits for the timeout to occur.
I've been running this code in production for a several weeks now and it seems to work well.
