Non-idiomatic 'is' type check for an object

Reports non-idiomatic is type checks for an object.

It's recommended to replace such checks with reference comparison.

Example:

object Foo

fun foo(arg: Any) = when {
    arg is Foo -> ...
    arg !is Foo -> ...
}

After the quick-fix is applied:

object Foo

fun foo(arg: Any) = when {
    arg === Foo -> ...
    arg !== Foo -> ...
}
