Add prefer-reflect exception

[jasonkuhrt]

apply is a common function name (e.g. Ramda) but ESLint prefer-reflect rule is not very smart about detecting usage of Function.apply. Namely, if trips upon any .apply(...) regardless of its coming from Function or Ramda. This is annoying because of the frequency of apply. We should use the exception feature of prefer-reflect to disable tripping on apply.
