renaming mechanism seems to not checking event being cancelled properly

1. can be slightly complicated to explain
2. I code too, I know what I'm talking

plugins involved : McPets , Lands , Meg

Problem: /pets doesn't open GUI properly

Why the hell are you writing issue of McPets in here? -> let me explain

Facts

1. issue found that /pets command makes indexOutOfBound Exception
2. found out this is caused by malformed saved data of McPets
3. McPets save pet name in flatfile such as "petId;petCustomName" , ex ) "bear;myCuteBear"
4. McPets use meg rename mechanism to rename its pet
5. Lands is a protection plugin, and it has lands chat functionality whereas, it will cancel event AsncChatEvent, and send message to land members

Reproduce

1. enter lands chat mode ( /lands chat )
2. rename pet
3. breaks ( pet data is formed in "petid;" , name empty

My thinking

1. McPet should handle this exception , and put some default string if it can't read name properly -> problem: dev claims he's unavailable till April , and this issue was there for damn 2 months
2. Lands Chat is not culprit, as he's just doing his job
3. It probably could be handled by checking if event.isCanclled() return; by not renaming model name if chat is cancelled. -> obviously won't fix malformed data of McPets, but they could be handled. just need this not to be happening more.
