Fix bundler test failures.

These failures are caused by the incompatibility in keyword argument
treatment in rspec-mocks.
I fix the expectations in the bundler/rubygems_integration_spec.rb.
These tests are not touched in the master branch.
It seems that the following patch also fix the failures.
But I believe the expectations in these tests are wrong. We should pass a Hash literal explicitly.
