[r4mbo7]

Hi! I planned to contribute but I got error running the tests out of the box. This PR fix errors I had:

rspec ./spec/active_interaction/base_spec.rb:224 # ActiveInteraction::Base with a filter .run(inputs = {}) passing validations failing runtime validations returns an invalid outcome
rspec ./spec/active_interaction/base_spec.rb:232 # ActiveInteraction::Base with a filter .run(inputs = {}) passing validations failing runtime validations has errors
rspec ./spec/active_interaction/base_spec.rb:239 # ActiveInteraction::Base with a filter .run(inputs = {}) passing validations failing runtime validations has detailed errors
rspec ./spec/active_interaction/base_spec.rb:228 # ActiveInteraction::Base with a filter .run(inputs = {}) passing validations failing runtime validations sets the result
