[bug] default state is sometimes invalid if the DB column has a default value too

[smudge]

TODO: Put the steps for reproducing this here.

I ran into this issue running steady_state on sqlite where you can't have a null: false column without a default. I'll write up a minimal repro and put together a pr in the next week or so.

This issue came up again. Adding default: 'pending' to the status column (in a migration) would make it impossible to start the state machine in any state that doesn't have from: 'pending' on it.

[smudge]

I think it would make sense for this gem to somehow detect when a column-level default is getting applied and raise a warning/exception.

This is possible! Here's an example:

irb> SomeModel.columns_hash['status'].default
=> "pending"

OMG running into this now too!
