Log:
[ruby/rubygems] Fix plugin new version not registering:

- ### Problem

When a plugin in the Gemfile is updated to a new version, it will
be downloaded but will not be registered. The old version of the
plugin will be loaded when Bundler is invoked.

### Context

The problem is in the `Index#installed?` method that only checks for
the plugin name in the index. If it finds one, it skips the
registration.

### Solution

Check whether the registed plugin load paths matche the new plugin
one. If not, register the new plugin which will override the
previous one in the index.
