This PR contains several small performance fixes for json-ld.

The optimizations consist in:

  • applying recommendation of 'fasterer' gem (here Hash#each_key faster than Hash#keys.each)
  • removal of unused code in JSON::LD::Utils#debug that was executed even when debug is not on
  • refactoring expensive Array intersection in JSON::LD::Utils.node? for several Hash#has_key? calls
  • reduce allocation of Hashes by using Hash#merge! instead of Hash#merge when appropriate and safe

The specs still pass after all these changes.
