delete method is not required in custom storage

[davidwneary]

Not sure if this is an issue or a deliberate choice but it seems strange to me that custom storage options don't need to have a delete method. This just tripped me up when I was migrating from using simple storage (which has a delete method) and mongodb store.

My use case is that when I get an account_invalid response when attempting to start an RTM connection I want to delete the team from my records since they have uninstalled the app.
