mw.htmlform: Fix 'hide-if' disabling OOUI fields

Follow-up to 5d5dbc83da4bc339e6c2f7fb3d346ba259192b68.

The logic here is supposed to be the same as in the block above, but
it was inverted. I think this code used to be `.setRequired( false )`
at some point, and I changed the 'setRequired' but forgot the 'false'.
