Fix typogrifying objects without title

[rr-]

This fixes my use case where I use readers.read_file from within a plugin to load something that is neither a page nor an article and it makes little sense for it to have a title, but it has metadata and content that should be parsed like the rest of the objects.

Looks fine to me. Maybe even pull it out of the if content block so that all 3 of the conditionals are independent from one another?

The pelican_comment_system also needs this fix. It uses readers.read_file on comments which don't have a title.

I didn't run into this error earlier since I don't use typogrify.
