Abstract over list of application creation to minimize code duplication

[michaeldiamant]

For illustrative purposes, abstract over list of application creation to minimize code duplication.

Notes:

• As a way to boost my Python learning while reviewing on Tests: E2E testing C2C with ClearStateProgram algorand/go-algorand#3693, I replaced imperative application creation calls with a helper method.
• The PR's minor novelty is using more-itertools to abstract over partitioning a list of errors and transaction infos.
• Since the imperative logic is also relatively straightforward, I don't expect to have the PR merged. I'm posting it in case there's other folks new to Python that can benefit from seeing the before/after transformation. Though if we wish to merge it, I'm open to feedback.
