Jmockit Expectations - Handle Additional Cases

[tinder-dthomson]

What's changed?

• Refactored the recipe to visit J.MethodDeclaration instead of J.NewClass. When attempting to substitute the J.NewClass with multiple J.MethodDeclaration LSTs, the old recipe would fail.
• Added support for multiple expectations statements.

What's your motivation?

Continuation of #415.

This is still an incomplete implementation, but now handles multiple expectations defined within a JMockit Expectations block.

Anything in particular you'd like reviewers to focus on?

Anyone you would like to review specifically?

Have you considered any alternatives or workarounds?

Any additional context

Checklist

• I've added unit tests to cover both positive and negative cases
• I've added the license header to any new files through ./gradlew licenseFormat
• I've used the IntelliJ IDEA auto-formatter on affected files

Thanks for this improvement already! Would you want to continue to iterate in this pull request? Or can we merge the existing work and follow up in a subsequent PR?

I'm okay with iterate PRs, since this will take some time to cover all cases.

Thanks a lot for these improvements already, we can indeed iterate in a follow up PR; We'll get this merged and released already.
