Bug 26833: Logged in library doesn't show with suggestions count

This patch corrects the template variables used by the suggestions
counts shown on the staff interface home page and the acquisitions home
page. They should use [% Branches.GetLoggedInBranchname %]

To test you should have some suggestions from multiple libraries.

- Log in to the staff interface.
- On the home page you should see "Suggestions pending approval,"
  followed by the name of your logged-in library and the count of
  suggestions for your library.
- Go to the acquisitions page.
- In the "Pending suggestions" section you should see the same
  information: Your logged-in library name, suggestion count, and the
  count of suggestions at all libraries.
