RedisStorage major fixes + tests updates

[Olegt0rr]

Description

Forget to add async for Redis .close() coro.
Thanks @darksidecat for comment #649 (review)

By the way fixed some bugs and fixed tests.

• adapter redis init
• await close
• string typing (to prevent aioredis compatibility issues)
• skip tests for RedisStorage v1 with aioredis v2
• fixed lazy fixture issue
• fixed connection pool test issue

Sorry for large PR, but only merge of all of this issue fixes make able to test redis support correctly.

See that redis_storage_2 tests failing with

self = <aiogram.contrib.fsm_storage.redis.AioRedisAdapterV1 object at 0x7f78aa61c9d0>
name = 'fsm:1234:1234:data', kwargs = {}

    async def get(self, name, **kwargs):
>       return await self._redis.get(name, encoding="utf8", **kwargs)
E       AttributeError: 'NoneType' object has no attribute 'get'

../aiogram/contrib/fsm_storage/redis.py:310: AttributeError

Seems like await self.get_redis() should be called in some of AioRedisAdapterBase, AioRedisAdapterV1 methods for settling self._redis
