fix: Include source url for parsing failures

[timfish]

Since #106 might not get merged, I cherry picked the improvements to logged error messages when module wrapping fails due to parsing failures.

processModule may parse multiple files in the process of wrapping a module so it's important to log the exact file the fails parsing.

Do not use NODE_ENV. I provided feedback in #112 that we should use Node.js's native feature for issuing warnings.
