[rubygems/rubygems] Fix `bundle exec gem uninstall`

* `bundle exec` assigns `Gem::Specification.all` to the set of specs
  known to Bundler (a `Bundler::SpecSet`).

* `gem uninstall` recently started calling `#delete` on the set of specs
  stored in `Gem::Specification#all`. This, in RubyGems, is just an
  array of specs, so has a `#delete` method that receives a single
  element.

* However, at some point I added a `SpecSet#delete` method that takes an
  array of specs, breaking the "Array-like" contract and making `gem
  uninstall` break when run in a `bundle exec` context.

The fix is to make `Bundler::SpecSet#delete` handle being given a single
spec.
