Describe the bug

If you attempt to read the last entry of an empty stream using XREAD STREAMS blah +, you get an error. It should be returning nil instead.

To reproduce

127.0.0.1:6379> xgroup create blah blah 0 MKSTREAM
OK
127.0.0.1:6379> xread STREAMS blah +
(error) ERR the stream last element ID is 0-0

Expected behavior

Valkey should return a nil response instead of an error, as with Redis:

127.0.0.1:6379> xgroup create blah blah 0 MKSTREAM
OK
127.0.0.1:6379> xread STREAMS blah +
(nil)
127.0.0.1:6379>

Additional information

This happens use the latest valkey/valkey:alpine image.

The source indicates this error should be impossible.
