[w3c/permissions] previousResult not really stored anywhere (#234)

The |previousResult| var is mentioned up in various algorithms, but is not stored anywhere persistently... it also feels like an optimization (if you have a cached one, return it). Could we either:

1. put it somewhere as an internal slot. 
2. drop it.

My preference would be to drop previousResult. Caching a string (enum) value doesn't seems particularly useful.
