Bug 34406: Fix inconsistencies in Identity providers/domains page titles, breadcrumbs, and headers

This patch fixes some inconsistencies in the templates for identity
providers and identity provider domains, making sure the page title,
breadcrumb navigation, and page headers are consistent with each other.

To test, apply the patch and check these views:

- Administration -> Identity providers
  - New identity provider
  - Edit identity provider
  - Confirm deletion of identity provider
  - Manage domains
    - New domain
    - Edit domain
    - Confirm deletion of domain
