Title: fix for auto-generated casette name when "it" block in rspec has no description

```ruby
decribe A do
descirbe 'test', vcr: true do
before { do_some_http_request }
subject { true }
it { should be_true }
end
end
```

This example generates file with name `spec/vcr_cassettes/A/test/.yml` but should generate `spec/vcr_cassettes/A/test.yml`
