Title: update Hash#slice to behave more like the one in ActiveSupport

I was trying to use facests with some code written originally for ActiveSupport Hash#slice and ran into trouble because it assumed that it was OK to supply keys as arguments to #slice that weren't necessarily in the hash. I don't see any reason to be strict in this regard, so I've updated the implementation to follow the behavior.

I've updated the tests to verify this behavior as well.
