Disappear speaker badge from WordCamp Tokyo 2017 speakers

[mayukojpn]

Contributors who speak at WordCamp Tokyo 2017 lost speaker badge.

e.g.
​https://profiles.wordpress.org/mignonstyle
​https://profiles.wordpress.org/toro_unit
​https://profiles.wordpress.org/hideokamoto
​https://profiles.wordpress.org/bryceadams
​https://profiles.wordpress.org/mikeschroder
​https://profiles.wordpress.org/noel_tock

Past speakers who don't speak this year still have badges:

I'm not sure if it happened before #3036 or not.

I could fix from dashboard!

• remove the wordpress.org username
• save the post
• put the username back in
• then save the post again
• that should fix it
