Add automated test to check chapter titles display in entire work view when work has only a single posted chapter

Description

For a long time, we had AO3-4150: The chapter 1 title of a work with only one posted chapter isn't visible in Entire Work mode

That got fixed as a side effect of this pull request for a different issue.

We should now add tests so it doesn't mysteriously break on us.
