Faces 1690 similar to FACES-1638

Faces 1690 marked as duplicate because it was similar to FACES-1638.  In solving the issue, I created a resetParameterMap method in LiferayBaseURLImpl. Called this new method when it "seamed" appropriate in LiferayPortletURLImpl. We may also need to look at Liferay_oTHEr_URLImpl(s) such as LiferayResourceURLImpl, and consider the following proverb (14:12): There is a way that seems right to a man, but its end is the way to death.
