A wrong exception is raised when prefix from the setup does not match a prefix in a passed key

[simon-liebehenschel]

Code example

import asyncio
from cashews import cache


async def func():
    cache.setup("mem://", prefix="foobar")
    await cache.set(key="spameggs:key", value=42)


asyncio.run(func())

Current behavior

A misleading confusing error:

cashews.exceptions.NotConfiguredError: run `cache.setup(...)` before using cache

Expected behavior

Raise an exception with a correct message.

Fixed - now it will raise

cashews.exceptions.NotConfiguredError: Backend for given key not configured
