agent_ui: Clear error message callout when message is edited or added in same thread (#33768)

Umesh Yadav created 5 months ago

Currently if error occurs in the agent thread and user updates the same
messages or sends a new message the error callout is still present and
is not cleared. In this PR we are clearing the last error in case user
sends a new messages or resend the previous message after editing.

Release Notes:

message is edited or new a message is send.
