Radan Skoric 26b35a4096 Fix ActiveModel::Errors#delete return value to stay backward compatible ... Rails 5.0 changes to ActiveModel::Errors include addition of `details` that also accidentally changed the return value of `delete`. Since there was no test for that behavior it went unnoticed. This commit adds a test and fixes the regression. Small improvements to comments have also been made. Since `get` is getting deprecated it is better to use `[]` in other methods' code examples. Also, in the module usage example, `def Person.method` was replaced with a more commonly used `def self.method` code style.		2015-03-22 23:18:22 +01:00
