UAST: remove redundant override: expression list's evaluate()

The super function in `KotlinEvaluatableUElement` is almost same,
except for handling of `UnsignedErrorValueTypeConstant`.
Such handling was added later, so I assume the addition to this override
was missed. In any cases, this override is unnecessary.
