Title: Use the correct version constraint for the RSpec dependency

The current release of RSpec is v3._x_. It is incompatible with the specs defined in amq-protocol due to the elimination of such constructs as `its` blocks.

Without this change to the version constraint, the project’s specs cannot be run after bundling on an empty gemset.
