[module-jni] bug in handling Qore constructor calls when backing dynamic Java classes

[davidnich]

the internal logic for detecting if a Qore class is backing a Java class is invalid:

Unexpected exception: OBJECT-ALREADY-DELETED at /export/home2/dnichols/src/Qorus/current-ce/qlib/RestClient.qm:457 (Qore)
