Before this patch mc sstables writer was ignoring
empty cellpaths. This is a wrong behaviour because
it is possible to have empty key in a map. In such case,
our writer creats a wrong sstable that we can't read back.
This is becaus a complex cell expects cellpath for each
simple cell it has. When writer ignores empty cellpath
it writes nothing and instead it should write a length
of zero to the file so that we know there's an empty cellpath.
Fixes #4533
Tests: unit(release)
