Added Default org and loc selection support to users.

We now have support for `default_org` and `default_loc`,
selection under the org and loc tabs for the users.

This PR is already "REBASED". will rebase again if required.
It's functionality is not so. What it does is it fetches whatever the current selected option is from the dropdown. 

From the selenium module selenium/webdriver/support/select.py

```
@property
    def first_selected_option(self):
        """The first selected option in this select tag (or the currently selected option in a
        normal select)"""
        for opt in self.options:
            if opt.is_selected():
                return opt
        raise NoSuchElementException("No options are selected")
