Title: [Messages] In participant option menu, overlay display should only dislay unknown number/email once

https://bugzilla.mozilla.org/show_bug.cgi?id=920037

- Re-organize the assignment of OptionMenu params
- Clear params.section if the participant is an unknown participant
- Update tests
- assert content of params.header value
- assert that params.section is an empty string for unknown participants
