Signal.pkg.recipe fails on PathDeleter Processor

[SeanHansell]

Consistently receiving this error. It works fine when the PathDeleter processor is removed. I believe AppPkgCreator does this automatically now.

Crystallized's Signal PKG Recipe doesn't work either, for a different reason. Hoping one of you can fix this, so I don't end up rolling a third. I'll open a PR with the change but let me know if there's anything I can do.
