Show the deploy branch in the app page title (closes #240)

The app page shows the app's configured branch as a neutral label next
to the status badge, so it can be read without opening the edit page.
The line under the title now shows only the repository. A new test
renders the app page for an app on a non-main branch and checks the
branch is in the title row.
