Show No Requests By Default

Purpose: Requests app currently shows all requests (open and closed) when you open the app. This is too much noise and the most common workflow is to search for a specific request anyway. With that in mind, we'd like to modify the Requests app so it behaves like Users. No requests should display unless a search or filter is applied.

User story:
As a user who has opened the Requests app
I don't want to see any requests until after I have applied a search or filter
So I am not overloaded with unecessary noise

Scenarios

1. Scenario
   • Given the Requests app
   • When first accessed
   • Then:
     • No requests should display in the results list
     • Results pane should display this message "Choose a filter or enter search query to show results" (same formatting as in Users app)
     • Results will only display when search terms and/or filters are applied
