Returning the result of the symbol evaluation for ios format

[avanrielly]

Pull Request

Summary:
Making sure to return after evaluating an iOS symbolized format method.

Related Issue:

Description:
Right now, the Noticed::DeliveryMethods::Ios#format_notification method is setup to handle a proc, symbol or message. When the symbol version of the format method is used, it evaluates the symbol using send and then calls notification.instance_exec with the result from the event.send call. This causes an error in execution.

Testing:
This was tested to work on my local machine against our codebase.
