fix(poller): Resource leak in IssueListOverview (#102053)

Replication steps:
1. Go to IssueList. Set filter by project-1. 
2. Turn on realtime. 
3. See the network requests for project-1.
4. Select filter by project-2.
5. See the network requests both project-1 and project-2.

`CursorPoller` has a recursive `setTimeout` method. If the poller is not
cleaned up for `project-1`, the recursive method will keep calling
itself and preventing garbage collector from killing it.
