MethodGroupHelper ignoring empty args when sending query but not when building sig

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Using Notifications.send make a valid call leaving the email argument blank
2. Signature is hashed including the email as an argument
3. Query string is built and continues past the email argument because it
is blank

What is the expected output? What do you see instead?
Facebook API should respond with notifications_send_response but instead
you receive an Invalid Signature error.

To correct this add the following at line 127 of
com.adobe.webapis.facebook.methodgroups.MethodGroupHelper

if (args[j].value.toString().length==0) continue;
