Add integration tests for main.js

[smockle]

Part of #43

This PR adds tests for main.js, similar to the tests that already exist for post.js.

Specifically, it tests that:

• main exits with an error when GITHUB_REPOSITORY is missing.
• main exits with an error when GITHUB_REPOSITORY_OWNER is missing.
• main successfully obtains a token when…
  • …the owner and repositories inputs are set (and the latter is a single repo).
  • …the owner and repositories inputs are set (and the latter is a list of repos).
  • …the owner input is set (to an org), but the repositories input isn’t set.
  • …the owner input is set (to a user), but the repositories input isn’t set.
  • …the owner input is not set, but the repositories input is set.
  • …neither the owner nor repositories input is set.

Architecturally, in order to keep individual tests concise, this PR adds tests/main.js, which:

• sets commonly-used inputs, environment variables, and mocks, then
• calls a callback function that can edit the variables and add additional mocks, then
• runs main.js itself.

The tests/main-token-get-*.test.js test files run tests/main.js with various scenario-specific callback functions.

I prefer we don't use any module mocking, instead mock all requests and capture and snapshot all logs / thrown errors. Let me know if you need help with that

👍 Cool; removed esmock and tests using module mocks, in https://github.com/smockle/create-github-app-token/pull/56/commits/60504269230a68706c8bf9ed9e40ced513146235.

I added a happy path test (that mocks requests and validates stdout), in https://github.com/smockle/create-github-app-token/pull/56/commits/43f24998742aeb378c1e91e0fe6a0d790a0a6b92. @gr2m, is that what you had in mind?
