"Votes Submitted" user label disappears upon completion of voting stage

[vanderhoop]

As a facilitator,
I want the "Votes Submitted" indicators on user list items to disappear post-voting stage,
So that I do not have to visually parse information that is no longer relevant to my facilitation.

By Way Of Explanation: originally, this criteria lived in #294, but it felt like an enhancement, so I've extracted it out into its own story.

Acceptance Criteria:

• The "Votes Submitted" ribbon from allow facilitator to see who has completed voting #294 does not appear in non-voting stages.

blocked until #294, as it is an enhancement of that feature

implemented. closing!
