Tidy up fmt.println calls inside deploy_native_test and whitelist_native_test

[itamararjuan]

These tests we're added Println which seem to align some timers in the tests
The contract names collide otherwise being based on timestamp. We should consider what to do with this (either present a new counter variable which is added to the name for extra protection or something else which solves the problem)

To be dealt with after beta is out.
