name in handles dict not used in `mk_app`

[thorwhalen]

The following should work, but instead mk_app complains about duplicate name "".

from http2py import mk_app

handlers = [
    dict(
        endpoint=lambda x, y: x + y,
        name='add'
    ),
    dict(
        endpoint=lambda x, y: x * y,
        name='multiply'
    ),
]
mk_app(handlers)

he issue seems to be that the run_app function is not correctly using the name field of the handler dictionaries to create the route paths. Instead, it's using the __name__ attribute of the endpoint function, which is <lambda> for all lambda functions.

To fix this, you need to modify the _get_func_to_dispatch_handler function to use the name field of the handler dictionary when creating the route path.

I added endpoint.__name__ = name before returning endpoint. This was a omission since the code had this at the end of it:

func.__name__ = name
return func

That said, this is not a good way to handle this situation in my opinion.
When a function is specified for a handler, the long language specs needs to be created from it, and subsequently, the "name" field, not the __name__ attribute, needs to be used.

In general, we want to apply the convention rules as early as possible, expanding our input objects (e.g. functions) to the long language that explicitly tells the subsequent transformations what to do (here, for example, create the "name" field for a route, instead of endowing func with a __name__ to be used later.

I've created a TODO in the code, and will make an issue or discussion to remember to change py2http to handle the language transformations better.
