Tomasz Grabiec 710ec83d12 Merge "Fix the system.size_estimates table" from Kamil ...

Fixes a segfault when querying for an empty keyspace.

Also, fixes an infinite loop on smp > 1. Queries to
system.size_estimates table which are not single-partition queries
caused Scylla to go into an infinite loop inside
multishard_combining_reader::fill_buffer. This happened because
multishard_combinind_reader assumes that shards return rows belonging
to separate partitions, which was not the case for
size_estimates_mutation_reader.

Fixes #4689.
