fix(redisdb): correct kwargs None check in RedisDB.__init__

[zhouxinfei]

Description

Fixed the kwargs check in RedisDB.__init__() from if kwargs is None: to if not kwargs:.

Problem

The original code incorrectly checks if kwargs is None:, but kwargs is always a dictionary (even if empty) in Python, never None. This causes the fallback to setting.REDISDB_KWARGS to never trigger when RedisDB() is called without arguments.

Solution

Changed the condition to if not kwargs: which correctly checks for an empty dictionary.
