Wrong codefix for '== default' #41
Description
When I enabled this analyzer it correctly complained about checkedTypes == default,
But the code fix doesn't result in checkedType is null as expected but in default is null:
This is because the code tries to handle null == checkedTypes and only tests if the right hand is null:
expr.Right is LiteralExpressionSyntax { RawKind: (int)SyntaxKind.NullLiteralExpression }
