Random failures in `test_repair_regression`

[Flamefire]

The test test_repair_regression fails often but not always

thread 'test_repair_regression' panicked at modkit/tests/test_repair.rs:63:9:
assertion `left == right` failed: record 10fc76b1-f06f-42f5-9275-09cd438c1db5 not the same
  left: Record(tid: 3, pos: 57)
 right: Record(tid: 0, pos: 20)
stack backtrace:

   2: core::panicking::assert_failed_inner
   3: core::panicking::assert_failed
   4: core::ops::function::FnOnce::call_once

The failing results seem to be the same though.

Ok, I'll take a look into it.
