Fix #97

I'm 99% sure this should be reverted and switched to correct approach which is using break within each inner loop.

[Athozus]

Yep @S-S-X was too fast sorry. I don't really how to revert, let's do it and implement a proper way than I did.

[S-S-X]

Well, don't think there's need for actual git revert but if #entry.<insert-table-name> > 0 then are unnecessary and inner break is necessary.

I could try to explain whys better but I think writing simple test Lua script for nested loop behavior would give better idea, especially watching i and outer loop table length inside inner loop so you can see how it shifts past outer loop table length when last entry is removed while inner loop still has items to check.

At least we can just squash the thing and it's done ? Ok for the code part.
