[BUG] Not able to call the detect_intent in a particular environment

[tejesh4034]

Expected Behavior

I should be able to call the agent in a particular environment

Current Behavior

I can specify a environment, when I did it throws me an error

Possible Solution

Steps to Reproduce

1. call the Sessions.detect_intent() method with a session url that has the environment ID in it
2. example session_id url: projects//locations/us-central1/agents//environments//sessions/
3. 3. It will throw an error that session ID is not in the expected format.

Context (Environment)

Detailed Description

s = Sessions()
s = Sessions(agent_id=agent_id)
session_id = s.build_session_id(agent_id).split("/sessions/")[-1]
session_url_with_environment = agent_id + '/environments//sessions/'+session_id
res = s.detect_intent(agent_id, session_url_with_environment, "hello")

Error: ValueError: Session ID must be provided in the following format: projects//locations//agents//sessions/.
