Throwable supplier never returns a value

Reports Supplier lambdas in Optional.orElseThrow() calls that throw an exception, instead of returning it.

Example:

optional.orElseThrow(() -> {
    throw new RuntimeException();
});

After the quick-fix is applied:

optional.orElseThrow(() -> new RuntimeException());
