Support for Rails Engines

[frank-west-iii]

We are currently looking to implement this gem in a Rails Engine, however the Railtie initializer does not load.

https://github.com/amatsuda/database_rewinder/blob/master/lib/database_rewinder/railtie.rb#L4

I am not familiar enough with Railtie to understand what would need to be changed to make this work or if it is possible at all.

Do you know if this is possible to run in an Engine?

I uploaded a sample engine with the reproduced error here:
https://github.com/frank-west-iii/database_rewinder_engine

The error is:

bundle exec rspec spec

An error occurred in a `before(:suite)` hook.
Failure/Error: DatabaseRewinder.clean_all

NoMethodError:
  undefined method `empty?' for nil:NilClass

Finished in 0.01801 seconds (files took 1.09 seconds to load)
0 examples, 0 failures

Not sure this will help, but thought I would post it up just in case!
