Fix handling of ::class in Kotlin lexer (#1572)

Due to the way the Kotlin lexer treats the 'class' keyword, the use of the callable reference, `::class`, can result in the lexer moving into an incorrect state where it interprets `class` as beginning a class definition. This commit fixes that bug. Co-authored-by: Michael Camilleri <[email protected]>
