bug: subject helper error

[Nishchit14]

Describe the bug
When I use subject helper multiple time in the same function to check multiple permission then it's showing error

ability.can('create', subject('folder', {}));
ability.can('read', subject('chat',{}));

Error

Error: Trying to cast object to subject type chat but previously it was casted to folder

Cannot reproduce, If you look into code this error is thrown only if you try to change the type of previously used object - https://github.com/stalniy/casl/blob/master/packages/casl-ability/src/utils.ts#L25
