Force running validations on multiples

Collection Forms used `Enumerable.all?` to run validations. This
method short circuits at the first falsy value, so in the case of
[record1, record2, record3] where record2, and record3 are invalid
validations will not be run on record 3. This commit uses map to ensure
validations are run for all models, and the all? to check the result
array.
