setting distinctid after session already started, create another session and new visitor

[Vikaskumargd]

Describe the Bug

User Journey:

1. User go to landing page anonymously. (session started and visible in Umami Session page)
2. User now login/signup. (I am setting distinctid as userid using umami.identify(unique_id: string). Now new session started)

Now I have 2 different session visible on Session page with different visitors.

It should not be the case.
