This PR protobuf-ruby/beefcake#70 introduced changes that affect the integration test suite, causing these failures:

Failures:

  1) Encoding and CRDTs with utf-8 strings updates registers in maps
     Failure/Error: expect(map.registers[random_string]).to eq random_string

       expected: "🚴こんにちはสวัสดีibreqol3lt"

  2) Encoding and CRDTs with utf-8 strings updates sets
     Failure/Error: expect(set.members).to include random_string

Failed examples:

rspec ./spec/integration/riak/encodings/crdt_spec.rb[1:1:2] # Encoding and CRDTs with utf-8 strings updates registers in maps
rspec ./spec/integration/riak/encodings/crdt_spec.rb[1:1:3] # Encoding and CRDTs with utf-8 strings updates sets

The addition of dup means that the original string was no longer forced into binary encoding, and we must have depended on that behavior. I have to dig in further.
