When rendering file Entries, the EntryComposite originally would not
render the file list Combo if no files were in the workspace. I had
changed this with my last commit to fix a bug, but decided the original
behavior was probably desired. This commit restores that behavior but
minus the bug's exception.

Fixed a bug where the YAML/action syntax generator would append to
instead of overwriting old files.
