Fix to match the tag from the response to be exact as command sent

[jui8wang]

Fix to match the tag from the responses to be exact as the command sent when deciding all server responses are completed.

Description

Before, as long as we see tagged responses, we call it complete.

Motivation and Context

In case server sends junk characters instead of * or +, we will not treat it a tag response.
