Fix ReflectionMHTests for -Djdk.reflect.useDirectMethodHandle=false

Previously for JEP416, adjustments were made to ReflectionMHTests to adapt the
frames for method handles. This test was failing when
`-Djdk.reflect.useDirectMethodHandle=false` option is set. Adding an additional
check in the test to see if the property is set to true to call for
InjectedInvoker check.
