add testcases for initial state

they fail to load due to a missing Simon object
add missing Simon object

now the testcases are loading but the assertions are failing like expected
because there are no sequence properties nor getRoundNo() function
implement initial state

the testcases are now passing as intended
add testcases for Simon's actions at the start of a new round

the testcases are failing due to missing functions pickRandomColor(), replaySequence() and nextRound()
add missing functions pickRandomColor(), replaySequence() & nextRound()

the testcases are now failing like expected
implement Simon's actions at the start of a new round

the testcases are passing as intended.
however, we haven't implemented pickRandomColor() so the sequence gets filled
with undefined instead of actual colors... we need to add one more test
