aiothreads: More Informative timeout message

[chrisjsewell]

From aiidateam/aiida-core#4745, it might be helpful to allow for a more informative error message here:

pytray/pytray/aiothreads.py

Lines 146 to 155 in 371b22e

	def await_(self, awaitable: typing.Awaitable):
	"""
	Await an awaitable on the event loop and return the result. It may take a little time for
	the loop to get around to scheduling it so we use a timeout as set by the TASK_TIMEOUT class
	constant.
	:param awaitable: the coroutine to run
	:return: the result of running the coroutine
	"""
	return self.await_submit(awaitable).result(timeout=self.task_timeout)

along the lines of:

def await_(self, awaitable: typing.Awaitable, exc_msg: str = ""):
    try:
	    return self.await_submit(awaitable).result(timeout=self.task_timeout)
    except TimeoutError:
	    raise TimeoutError(f"{exc_msg} after {self.task_timeout} seconds")
