PROV-103: Fixes of Provider Management UI crashes when we select provider from search result on openmrs platform 2.x.x

[josephbate]

Description of what I changed

1. Added a try catch method to load the NameSupport class from either rg.openmrs.layout.name or org.openmrs.layout.web.name depending on which one is required
2. Used reflection to invoke the "getInstance" method and also getDefaultLayoutTemplate" method to creat objects
3. later invoked the instance object to get the layoutTemplate

Issue I worked on
