Name of API affected:
Analytics Data Export API

Issue summary:
mixing adCost with itemQuantity and with the medium dimension (either as a 
dimension or as a segment) is causing the API to report adCost as 0 
although that is not true for cpc visits)

Steps to reproduce issue:
1. create a Data Feed Query using dimension ga:month & metrics 
ga:itemQuantity and ga:adCost
2. add segment to query: dynamic::ga:medium=~cpc
3. run query

Expected output:
1 row of data for each month in the query indicating the item quantity and 
the ad cost for each month of cpc data

Actual results:
all data is correct except ad cost only reports 0 for every row.

Notes:
If I run the quantity and adcost report without the medium dimension or 
without the cpc dyanmic segment I get adCost right but obviously quantity 
includes all traffic.

I also have got problems with "ga:adCost"

I pull:
ga:goal1Completions, ga:visits, ga:adCost, ga:adClicks

by year, month and all data is correct, except adCost. That one sometimes shows 
a date or numbers that are 1000 times higher than the real ones.
