Adjusting Received Messages after OData Calls

When there is an error message you want to show to user is set as transition false as below(actually not a good example for real cases).

This kind of message will not be displayed by UI5's message manager automatically. The reason is this message is parsed as persistent false.

In order to display this automatically, we can change this attribute in the callback of OData calls. Then you see the error message as the left side.
