Feature: URI without param(s)

  A common source of difficulty when using VCR with the default matchers
  are non-deterministic URIs. If the URI changes on every test run (because
  it includes a timestamp parameter, or whatever), the default URI matcher
  will not work well for you.

  You can write a custom matcher to match URIs however you want, but for the
  common need to match on a URI and ignore particular query parameters, VCR
  provides an easier way:

      :match_requests_on => [
        :method,
        VCR.request_matchers.uri_without_param(:timestamp)
      ]

  `uri_without_param` also has a plural alias (i.e. `uri_without_params(:timestamp, :session)`)
