Unnecessary response urldecoding fails if response JSON is not a valid urlencoded string

[kalinochkind]

QueryEmail method applies java.net.URLDecoder.decode to the response. However, the response is a JSON, not an urlencoded string.

In most cases this is a no-op, but sometimes it can fail. For example, if the response JSON contains the following location value: "location":"%"
then response parsing fails with the following exception:

java.lang.IllegalArgumentException: URLDecoder: Illegal hex characters in escape (%) pattern - Error at index 0 in: "","
