[spotbugs] Fix FileReftableStack#equals to check for null

This fixes spotbugs warning NP_EQUALS_SHOULD_HANDLE_NULL_ARGUMENT.

This implementation violated the contract defined by
java.lang.Object.equals() because it did not check for null being passed
as the argument. All equals() methods should return false if passed a
null value.
