#search() session expiration

[jcoyne]

When doing a long running search (e.g. over the whole repository) it's possible to encounter a Rubydora::FedoraInvalidRequest:

/Users/justin/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/rubydora-1.7.4/lib/rubydora/rest_api_client.rb:26:in `block (2 levels) in <module:RestApiClient>': See logger for details (Rubydora::FedoraInvalidRequest)
