Delete low-value tests: processor_spec

These tests simply repeat the implementation.

Also, they fail when we upgrade sexp_processor from 4.7
to 4.10. Something about the timing of the spy. I was able
to make these test pass by converting from spies to traditional
message expectations, but I won't, because I don't want to keep
these tests anyway.
