98e3a99a88 Do not catch exceptions during final flush in writers destructors 
Since this hides real problems, since destructor does final flush and if
it fails, then data will be lost.

One of such examples if MEMORY_LIMIT_EXCEEDED exception, so lock
exceptions from destructors, by using
MemoryTracker::LockExceptionInThread to block these exception, and allow
others (so std::terminate will be called, since this is c++11 with
noexcept for destructors by default).

Here is an example, that leads to empty block in the distributed batch:
