fix #1321 avoid downloading default request handler and url service

This commit avoids downloading default request handler and url
services until they are really needed (especially, if a request
handler or url service is specified at the request level, it is
not needed to download the default ones).
fix #1323 Increase test timeout fot test MultiAutoInvalidDataModel in IE9
fix #1326 increase timeout for RobotTestCase on IE

since many automatic tests fail on IE (especially on IE7-9) due to its slowness, a longer timeout will reduce them.
close #1326
