Title: add stub_any_instance method

Because sometimes we want to stub some method on all instances of the class.
@zenspider wdyt? Should this be in minitest or it can live as a helper or something? (we have it as helper already in [SimpleForm](https://github.com/plataformatec/simple_form/blob/master/test/support/misc_helpers.rb#L27))
