LPS-38558 - HTML markup in portlet search bar is incorrect

Hey @physicsfreak1,

Attached is an update for http://issues.liferay.com/browse/LPS-38558.  Can you check to make sure the changes did not break anything?  I think I found all instances that had to be changed for <aui:nav-bar-search>, but if there are more, please go ahead and make the changes and send me a new pull request.

Please let me know if you have any questions.  Thanks!
