UI:Added Location Function, Added more entity factory functions and Location tests

1) Added Update function for location entity
2) Fix navigation:
a) Currently tests have to navigate each and every time, when [updating or searching] which is undesired.
b) Moved the "navigation to the right entity's page" to it's search function, as every update function also have to call in search function.
c) Updated org tests to use the common locators for ORG and LOCATION
d) Add new Location tests module with new testcases.
