Fix 400 return code on SAF errors

[richard-salac]

Describe the bug This is a complementary issue to https://github.com/zowe/api-layer/issues/3007

There is the mapping between SAF errors and http return codes with one specific handling for error 8/16/28 mapped to 400. It is the only one SAF error with distinguished return code with seemingly no specific reason. I suggest to unify the error mapping to 500.

https://github.com/zowe/api-layer/blob/32793d87d6c10d15ff8a8ef1fb5213b91ec87bee/common-service-core/src/main/java/org/zowe/apiml/passticket/AbstractIRRPassTicketException.java#L65

Expected behavior Return 500 as for the other SAF error messages as 400 should indicate malformed request rather than permissions issue
