Same file subclasses are missing from permits clause of a sealed class

Reports sealed classes whose permits clauses do not contain some of the subclasses from the same file.

Example:

sealed class A {} final class B extends A {}

After the quick-fix is applied:

sealed class A permits B {} final class B extends A {}
