Minor improvements to Applications application

Summary:
I missed these in review, but here are a couple of tweaks:

  - Call `setWorkflow(true)` on the actions. This makes the dialogs pop up on the same page with Javascript if it's available.
  - When the user installs/uninstalls an application, send them back to the application's detail page, not the application list.

Test Plan:
  - Uninstalled an application (saw dialog, got sent back to detail page).
  - Installed an application (saw dialog, got sent back to detail page).
  - Canceled an application uninstall.
