WARNING: wordlist size mismatch (size=18, checkpoints=0)

[klirichek]

Bug Description:

It looks like we have wrong processing of an empty dictionary loading/writing

CREATE TABLE x ( id bigint, tag bigint );
insert into x values (1,1),(2,2),(3,3);
flush ramchunk x;
insert into x values (4,1),(5,2),(6,3);
flush ramchunk x;

Notice: table contains no ft.

Bug 1. .spi file (when flushing to disk chunk) has size 1. That is wrong, since it should include 'dict-header'
Bug 2. (unrelated) total_bytes in .meta is 0. Looks strange.

optimize table x option cutoff=1;

• .spi file after merging 2 chunks has right size 18.

Bug 3. WARNING: wordlist size mismatch (size=18, checkpoints=0)

UPD: 913b35a is relevant (seems need to revert it, then fix the warning)

I can reproduce the warning WARNING: wordlist size mismatch (size=18, checkpoints=0) in the latest dev, but not in 6.2.12.
