Fix displaying of user status

Summary:
This fixes two separate issues:

# `getTextStatus()` is used for machine readable data in handles and user.info method. Broken since D3810.
# Status may contain date. Broken since beginning but masked by the fact that CSS ignores unknown class names.

Test Plan:
Displayed revision with reviewer away.
Called `user.addstatus`.
Edited status in calendar.
