Room aliases list doesn't take into account multiple m.room.aliases states

The Room.update_aliases method does not take into account that there can be multiple m.room.aliases states. Because room aliases from separate HSes are in separate m.room.aliases states (with the HS name as the state key), this means the update_aliases function will actually set the aliases list to only contain the aliases from one HS, disregarding the others.

Example (the code should list all aliases for Matrix HQ):

>>> client.rooms['!cURbafjkfsMDVwdRDQ:matrix.org'].update_aliases()
True
>>> client.rooms['!cURbafjkfsMDVwdRDQ:matrix.org'].aliases
['#matrix:utzutzutz.net']

从 matrix_client/room.py 中的 Room.update_aliases 开始，然后复现 Matrix HQ room 的示例。检查每个 m.room.aliases 状态是如何处理的，并验证生成的 aliases 列表包含来自每个 homeserver 状态的 aliases，而不只是来自其中一个。
