[Merged by Bors] - Fix try/catch/finally related bugs and add tests

[jedel1043]

This Pull Request fixes some bugs related to try blocks:

• Fixes a panic when a finally block contained variable declarations. (Thanks to @VTCAKAVSMoACE for the report!)
• Fixes a bug where try blocks in the last position of a statement list didn't return its inner last value as the result of the evaluation.
• Add tests for both cases and two other common cases.
• Extract and cleanup some code.
