Calls to `clone` does not create an alias

[akwick]

CogniCrypt and Ruleset used: v2.7.1
Simplified jar-file: MessageDigestClone.zip

Analyzed code (excerp):

MessageDigest md = MessageDigest.getInstance("SHA-512");
MessageDigest c1;
c1 = (MessageDigest) md.clone();
c1.update("ABC".getBytes()); // doesn't change the reported misuse
byte[] part1 = c1.digest(); // doesn't change the reported misuse

Observed behaviour:
CogniCrypt reports an IncompleteOperationError:

in Method: void main(java.lang.String[])
                IncompleteOperationError violating CrySL rule for java.security.MessageDigest (on Object #21334a6508c8e9b9d3a43e9e47be125f2820991e8ca23877503bb4947a169144)
                        Operation on object of type java.security.MessageDigest object not completed. Expected call to digest
                        at statement: $r5 = virtualinvoke r1.<java.security.MessageDigest: java.lang.Object clone()>()

Expected behavior:

As clone() creates a shallow copy of md, c1 is an alias of md. Thus, the operation isn't incomplete and no report is expected. (Already discussed with @kruegers )

However, as clone() can also create a deep copy - if implemented - and the byte code handles md and c1 as two separate objects, I am fine with another solution as well.
