The 'deletion' strategy does not exist for the mongoid ORM!

[Victorcorcos]

On the README file, there is a section that says only the :deletion strategy is available on mongoid. However, it seems like it is quite the opposite, only the :truncation strategy is available.

I tried to use the :deletion strategy and the following error message is displayed:

> DatabaseCleaner[:mongoid].strategy = :deletion

Is the README outdated?

Please take a look at the README section below...

Supported Strategies

The mongoid adapter only has one strategy: the deletion strategy.

@Victorcorcos Yes, you are correct. The behavior of the most recently released version of database_cleaner-mongoid (v1.x) does not match the README on Github because the master branch is tracking the upcoming v2.0 release, which makes some breaking changes, including renaming the Mongoid strategy from :truncation to :deletion. If you would like to open PR to update the README with a note about this, I'd merge it. You can copy the notice from the main database_cleaner repo.
