test: EdenFS correctly reports removed directories as directories
test: EdenFS correctly reports removed directories as directories

Summary:
Previously, EdenFS would report removed directories as files being removed,
which meant that Watchman would report these as files removal. Now that EdenFS
publish the file type of the file/directory being removed, Watchman correctly
reports the directory as being removed.

Note that there is still one issue for non-commit directory removal. This will
be fixed when EdenFS's Journal is made aware of file types.
