04_removeFromArrray: missing test case

[damon314159]

Because

A learner popped into discord to show off their code that passed all the tests. It used the splice technique many learners go for. This creates a problem for most learners for the test that removes all elements, since splicing changes the indexing and they will skip over some elements. However this particular learner had nested loops for the rest parameter and the source array, so this problem would only show itself if there were two adjacent entries of the same value to be removed.

This PR

Adds a test case to catch that scenario
