Fix eclipse compilation of hasValue (backport of #76375) (#76379)

In #76302 we removed a few warnings in a way that javac was happy with
but confused Eclipse. This makes eclipse happy by dropping our overly
strict bounds in `AggregationInspectionHelper`. We really weren't using
any of the type bounds we'd declared there at all.
