redis version: redis-4.1.4

#1848

This bug should fix in #1901.

Another pr #1993 overwrite it...

So the bug still unresolved

@ChandlerBent Thank you for reporting this bug again!

I'm afraid that this is happening again. Same example as above for a different query, redis_object_instance.execute_command with EXPLAIN works fine as described in the original issue and returns a list of bytestrings.
