State `dealing` without players

[sunify]

1. Two players at the table
2. One of them leave in dealing (not sure at 100%)
3. The player is allowed to leave and hand won't complete
4. One player at the table in dealing (with bet!)
5. The player is leaving. Result: empty table in dealing

When new players will sit at the table, game won't start until state won't be changed to waiting

Looks like 2. is not correct. Tried to reproduce it, but without success
