Gleb Natapov 4200e52444 storage_proxy: do not crash on LOCAL_QUORUM access to a DC with zero replication ...

If a table that is not replicated to a certain DC (rf=0) is accessed
with LOCAL_QUORUM on that DC the current code will crash since the
'targets' array will be empty and read executor does not handle it.
Fix it by replying with empty result.

Fixes #8354
