[db-sync] Format test file + increase 2 test timeouts

[jankeromnes]

Description

This increases the default test timeout 2s → 10s for these two slow 'Basic unidirectional replication' tests:

• 'Should overwrite outdated values and keep newer ones intact'
• 'Should pick up from the last replication time'

Fixes flaky test failures like https://werft.gitpod-dev.com/job/gitpod-build-main.3560 :

  1) Basic unidirectional replication
       Should overwrite outdated values and keep newer ones intact:
     Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.
      at listOnTimeout (node:internal/timers:559:17)
      at processTimers (node:internal/timers:502:7)

  2) Basic unidirectional replication
       Should pick up from the last replication time:
     Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.
      at listOnTimeout (node:internal/timers:559:17)
      at processTimers (node:internal/timers:502:7)

How to test

1. Should still build & pass all tests (hopefully without timeouts)

Release Notes

Whoa, that was fast. Many thanks! 🚀

And apologies for the cross-fire (I found the change too hard to read, so I split the formatting and the semantic change into two commits -- but it should still be exactly the same change).
