Include program in URL when searching in /learners

[briangrossman]

Currently, when you search in /learners, it implicitly searches within the currently selected program. It would be helpful to include the program in the URL querystring when searching to ensure that you will receive the same results if you share the URL of the search. (This was an issue recently on a Zendesk ticket)

The program can be specified using program=. If the user doesn't have access to the specified program, they should get a message:

You do not have access to the [program name - e.g. 'Finance'] program. Please choose a different program from the pulldown or enroll in [program name - e.g. 'Finance'].

Note that updating the facets currently updates the URL querystring.
