Subject: [PATCH] [rubygems/rubygems] Reset `Gem.state_file` along with
 `Gem.state_home`

As `Gem.state_file` is placed under `Gem.state_home` directory, when
the latter is reset, also the former should be reset.
If left unreset, the file for a previously run test will be re-created
and will not be deleted.
