Fix the compactors order and compress the composer.lock file (#228)

Fix the compactors order:
- Run the PHP Compactor before PHP-Scoper which can remove the useless spaces since will print again
  each file
- Compress the JSON files after PHP-Scoper since PHP-Scoper will pretty print the scoped JSON files

Also ensure that the JSON compactor can compress the `composer.lock` files.

Closes #219
