OmniCounter.test.js doesn't test for cross-chain counter increment

[tushargargght]

As mentioned in docs:

The OmniCounter
OmniCounter is a contract that increments a counter -- but there's a twist. This OmniCounter increments the counter on another chain

But the same is not tested in the unit-tests.

Have opened #51 for the fix
