Rendering empty box for relationships

[KentGrigo]

When no information is provided about a relationship, an empty box is rendered. This box should not be rendered.

Below is an example that shows three cases:

• Correct: The circa year for the marriage of John Shakespeare and Mary Arden
• Incorrect: Empty box for Richard Shakespeare and Unknown, and for Robert Arden and Agnes Webb
• Incorrect: Empty box for Richard Hathaway (without registered partner)

Example:

@PeWu, I haven't had much time to look into Topola yet. Should this issue be moved there?

The code that needs to be changed is in https://github.com/PeWu/topola We can move the issue
