tests updated to reflect changes made to ExtendedLoadableComponent

Two tests are failing. These are the tests of pages that actually are
element containers on the products page: breadcrump and user panel. Its
an obvious result of moving the PageFactory.initElements(driver, this).
This is a sign:) to refactor such 'sub' pages to actual element
containers. This will be a next task)
Moved to araz solution of elements containers, failed. Going to move to html elements solution

Tests fails on Container elements with NullPointerException while
creating proxy for the field. No reason was found.
