Use original name so that PYTHONASYNCIODEBUG=1 show it

[thomasjpfan]

When using PYTHONASYNCIODEBUG=1, the names of the original async functions are hidden. For example, on main and running with this file:

from synchronicity import Synchronizer
from synchronicity.async_utils import Runner


async def blocks_event_loop():
    import time

    time.sleep(0.5)


s = Synchronizer()


@s.wrap
async def my_custom_name():
    await blocks_event_loop()


with Runner() as runner:
    runner.run(my_custom_name.aio())

I get this output:

Executing <Task finished name='Task-6' coro=<Synchronizer._wrap_check_async_leakage.<locals>.coro_wrapped() done, defined at .../synchronicity/synchronizer.py:258> result=None created at .../synchronicity/synchronizer.py:415> took 0.501 seconds

The Synchronizer._wrap_check_async_leakage.<locals>.coro_wrapped makes it harder to find where the issue is.

Nice catch! Before mergin - can you confirm this doesn't break the type stubs on the modal client somehow (by running inv type-check). I have a vague recollection about functools.wraps not transfering the iscoroutinefunction property, which at least historically had some downstream effects on type stubs (but that might have been fixed)
