HttpTrigger with empty methods does not to respond to all methods #84
Description
Based on the HttpTrigger docs, if the methods are left empty in the HttpTrigger definition, it should respond to all methods.
When not explicitly defined, the HttpTrigger annotation in Java generates an empty methods array in function.json. This means the function doesn't respond to any HTTP methods at all and is inconsistent with the docs and the way the trigger works in other languages.
