Subject: [PATCH] Fix redis-cli pubsub_mode and connect minor prompt / crash
 issue (#12571)

When entering pubsub mode and using the redis-cli only
connect command, we need to reset pubsub_mode because
we switch to a different connection.

This will affect the prompt when the connection is successful,
and redis-cli will crash when the connect fails:
```
127.0.0.1:6379> subscribe ch
1) "subscribe"
2) "ch"
3) (integer) 1
127.0.0.1:6379(subscribed mode)> connect 127.0.0.1 6380
127.0.0.1:6380(subscribed mode)> ping
PONG
127.0.0.1:6380(subscribed mode)> connect a b
Could not connect to Redis at a:0: Name or service not known
Segmentation fault
```
