Empty strings shouldn't be filtered from requests, as we have explicitly set some attributes to be optional and actually differentiate between null and empty attributes in the server side. So now, only attributes containing None are filtered and empty strings are actually passed to the server. Change-Id: Ia048d7de6bcbc12317930eeccc009b6b0db10e13 Closes-bug: #1420445
