callBuffer does not work with auto-pipelining enabled.

[Sophos-Elias-Vasylenko]

Simple to reproduce. Open a client with auto-pipelining, and do something like await client.callBuffer("eval", "return 'Hello, scripting!'", 0) or just await client.callBuffer("get", "wizard")

You will get an error like ReplyError: ERR unknown command 'return 'Hello, scripting!'', with args beginning with: '0'

It works properly if you use call instead of callBuffer. Seems like something fishy is probably happening in this vicinity with all the shuffling around of arguments

Not had time to investigate further.

Work-around is to add the failing commands to the auto pipelining exclude list.
