Duplicate entries in issue timeline

[dmach]

Description

I discovered that issue timeline contains duplicate entries while writing tests for a code that prints them on the command-line. The tests started randomly failing.

I'm always running the same commands in a predefined sequence.
The problem is, that the push_pull entry is sometimes returned twice.
Also, the duplicate entry gets mixed among the entries that are associated with actions performed after the push.

examples:

Timeline:
2025-07-24 09:16 Admin pushed 2 commits
2025-07-24 09:16 Admin pushed 2 commits
2025-07-24 09:16 Admin changed title
    | from 'Change version' to 'NEW TITLE'
2025-07-24 09:16 Admin commented
    | test comment

Timeline:
2025-07-24 09:24 Admin pushed 2 commits
2025-07-24 09:24 Admin changed title
    | from 'Change version' to 'NEW TITLE'
2025-07-24 09:24 Admin pushed 2 commits
2025-07-24 09:24 Admin commented
    | test comment
