Java: Limit the amount of results that MissingEnumInSwitch produces per switch

The tool status page warns:
    An analysis file contained multiple alerts that included more related
    locations than our allowed limit of 100.
    These alerts correspond to the rule java/missing-case-in-switch.
    Only 100 locations were stored for these alerts.
