Replace the use of `asyncio.get_event_loop()` with more appropriate `asyncio.new_event_loop()` to create event loops for testing. The former used to be a wrapper that either returned the currently running event loop or created a new one, but the latter behavior was deprecated and removed in Python 3.14. Since the tests are always run in a synchronous context, and they always run the obtained event loop to completion, just always create a new event loop.

Remove the `asgiref` pin linked to prometheus#1020. I can't reproduce the issue anymore with the current `asgiref` versions, and the pin actually breaks the tests with the `asyncio` event loop fixes. Signed-off-by: Michał Górny <mgorny@gentoo.org>
