Record all UseCase calls

[JanOwiesniak]

Example

interface.my_domain(:my_use_case, { :something => '42' })
interface.my_domain(:my_use_case, { :something => '21' })

Current Behavior

My first call is gone.

interface.call_count[:get_ranking] # => 2
interface.calls[:get_ranking] # => {:get_ranking=> {:something=>"21"}}

Expected Behavior

Both calls should be available.

interface.call_count[:get_ranking] # => 2
interface.calls[:get_ranking] # => {:get_ranking=> [{:something=>"42"},{:something=>"21"}]}

It's a bug, true :+1:

I think it's from here:

https://github.com/neopoly/rohbau/blob/master/lib/rohbau/interface.rb#L53

There's only one stub result stored per call name at a time.
