There's a change that seems unrelated, making an argument into an array, but because upgrade can work on multiple contracts at once the way to obtain the contracts that need to be pushed gets us an array. I think in practice it will always be of length 1 but we can't be sure.
There are no tests in this PR because we currently have no tests for implicit commands like push is for update.
Fixes https://github.com/OpenZeppelin/openzeppelin-sdk/issues/1508. Fixes https://github.com/OpenZeppelin/openzeppelin-sdk/issues/1507.
