-= float operation used on None with timeout variable

[Mo-to]

In the loop in lines:

nostale_utils/utils.py

Lines 183 to 187 in e872596

	while result is None and (timeout is None or timeout > 0):
	await asyncio.sleep(0.05)
	timeout -= 0.05
	return result

If the variable timeout is None the operation timeout -= 0.05 would cause an error because timeout is None.
Change line

nostale_utils/utils.py

Line 185 in e872596

timeout -= 0.05

to:

if timeout is not None:
     timeout -= 0.05
