Subject: [PATCH] message dialog: use title style only if there is secondary
 text

If there is no secondary text, then the primary text is just a message,
not a title, and should not use title style.

This partially reverts 1e3ec7c1f993ec8cab4c6608b968e78f9028d662. The
message dialog nown looks like it used to in GTK 3. However, it's still
styled only using a style class rather than using pango markup, as in
GTK 3.

Fixes #3509
