XML Files Not Cleaned up Upon Job Deletion

Problem/Motivation

When translations are submitted to Smartling, the module generates two XML files, one in [schema]//tmgmt_sources/ and another in [schema]//tmgmt_smartling_translations/. These files are managed files. When the job entity is deleted, the files are not deleted.

What is the expectation for XML file clean up?

Steps to reproduce

1. Run a translation job.
2. Verify the XML files are downloaded to the file system.
3. Delete the translation job.
4. Observe the XML files are not removed.
5. Run cron (maybe there's a clean-up task).
6. Observe the XML files are not removed.

E.g. Here's example data from the file_managed table for a file associated to a deleted job:

mysql> select * from file_managed where filename LIKE "%JobID201_en_es.xml%";
