test(connector-besu): migrate v21-invoke-contract.test.ts to Jest

[petermetz]

1. No other changs in the test case - just what was strictly necessary
   to make it work with Jest.
2. Also updated the configuration files of the test runnres in the CI
   so that the test case gets ignored by tape and included by Jest
   (the oppositve was true/necessary prior to this change)

LGTM (I will wait for these jest migrations to be merged because I am adding/modifying these test cases to address #963 )
