fix(supervisor): failing tests, chores

[0x009922]

Context

4716 broke some tests.

Solution

This PR fixes kura_not_miss_replace_block, increases timeout for can_monitor_os_thread_spawn (broken in #4996), and does some other chores.

It doesn't fix restarted_peer_should_have_the_same_asset_amount as it requires deeper refactoring (WiP).

Checklist
