What
If you have an index that doesn't exist like Tire.index('foobaz') and call the method settings on it, it will error out due to a nil trying to be accessed like a hash.
This aims to fix that by returning a blank hash instead.
Since Tire.index('foobaz') returns an index even though one isn't made I figured this would be the approach you would like.
How to test
I put a spec in there to ensure that the error doesn't happen in the future.
Let me know if there's something I can change! Thanks!
