Indicate which file was being parsed if an exception is thrown while running translation:debug

When running the translation:debug command, if a template contains invalid twig markup,
an exception is thrown. This patch rethrows a new exception that includes the filename
being parsed in the message to aid debuging.
This seems like a better fix indeed :+1:
