[RUBY-2123] Add test coverage for symbol round-tripping in Hash field values - MongoDB Jira

The driver round-trips symbol values in hashes:

butler% irb -rmongo

irb(main):001:0> Hash.from_bson({foo: :bar}.to_bson)

=> {"foo"=>:bar}

This behavior is different from that of bson-ruby:

butler% irb -rbson

irb(main):001:0> Hash.from_bson({foo: :bar}.to_bson)

=> {"foo"=>"bar"}

As far as I can see there are no tests for this. This ticket is to add the missing test coverage.
