Description

An issue was also found where deleted files in a DiffX were getting a
default revision of PRE_CREATION, which caused the deleted file to
show up as new. This should have only occurred for newly-created files.

Now, missing revisions show up as UNKNOWN, making it more clear that
the revision is missing, and avoiding accidentally triggering this bad
state.

Testing Done

Unit tests pass on Python 2 and 3.

Tested this in production and verified that it fixed an issue with a
file appearing as new when it should have appeared as deleted.
