> Instead of asserting, ignore such calls, because they seem to always have

New description:
The `clock_skew_warning()` refactoring can cause an assertion failure when
`or_state_load()` calls to `control_event_bootstrap_problem()` (via
`clock_skew_warning()` prior to bootstrap phase 0.
We should initialize the bootstrap state first.
