Fix broken "name OR 'them'" logic

[erikras]

The way it was will never show name. In fact, I think we can probably assume that name is truthy when sharePage is, but if not, it should show the name, and fall back to 'them'.

Also, the 'them ' string had an extraneous space.

Thanks for this amazing repo! ❤️
