fix(es/decorators): Minimize class declarations transformation

BREAKING CHANGE:

Related issue (if exists):

I think we should check if the mutability of the variable (let/class) is identical, and if not we should add an assumption entry.

I'll check it using chrome

[kdy1]

These are not affected

class Foo {
    static {
         Foo = 1;
    }

}

let Foo = class Foo {
    static {
         Foo = 1;
    }

}

class Foo {
    static field = Foo = 1;

}

let Foo = class Foo {
    static field = Foo = 1;

}
