camel-sap: verify support SAP JCo 3.1 (3.0 out of support October 2020)

IHAC that complains about compatibility issue upgrading the SAP JCo lib from 3.0 to 3.1.

I haven't been able to set up a test case but I've requested it at the CU.

Meanwhile, can you check if the camel-sap tests still work with JCo 3.1?

The task is urgent (maybe it's too late) because JCo 3.0 will go out of support at October 2020 and the CU can't leave unsupported libraries in a production environment.
