[tarantool-patches] [PATCH] test: fix replica expectance in broken lsn test

[Ilya Kosarev]

xlog/panic_on_broken_lsn includes waiting for replica and then
box.info.vclock usage. Sometimes box.info.vclock was giving wrong
values. Now it is stable due to improved replica expectation
criterion.

Closes #4508
