Selector now handles non-ascii characters.

Removed the str type conversion as it was not needed.
Also added 2 tests to select organization and then location and
viceversa in their respective test modules.
This test case was added with the idea to test whether both the org and loc are selected successfully. When dealing with other tests for example like that of "Host" creation we would need to select both the org and loc.
On the UI front as selection of org and location are so closely related, meaning org and location are just seperated by "@" ,I thought it's desired to test selection of both the entities.
