Make sure we cover in a test the unary + conversion

Came up in the review.

We should make sure that + "1_0" is converted to 10 while using the unary plus operator (should be because it uses the Number constructor, but we wanted to sanity check).

@rwaldron

IIRC we intentionally set numeric separator to not affect string to number operations to avoid breaking the web. So + "1_0" will consistently evaluate to NaN and the separator tokens are only valid within Numeric Literals.
