SpliltHyperRectangleBridge can add 0-dim constraint

[odow]

A new bridge was added in #2754

• It rewrites f(x) in Interval(l, u) to [f(x)] in HyperRectangle([l], [u])
• SpliltHyperRectangleBridge rewrites [f(x)] in HyperRectangle([l], [u]) to [f(x) - l, u - f(x)] in Nonnegatives(2)
• Except if l or u are infinite then the rows are excluded in the nonnegative constraint
• Bug is that if both l and u are not finite, then we add Nonnegatives(0) constraint, which solvers like CSDP freak out at.

We should omit adding the constraint if all rows are free.
