When I tried TypeProf in VSCode, I got the following error:
```
/Users/sinsoku/ghq/github.com/ruby/typeprof/lib/typeprof/core/ast/sig_type.rb:503:in `typecheck': undefined method `each' for nil (NoMethodError)
@types.each do |type|
^^^^^
from /Users/sinsoku/ghq/github.com/ruby/typeprof/lib/typeprof/core/graph/box.rb:152:in `block in match_arguments?'
from /Users/sinsoku/ghq/github.com/ruby/typeprof/lib/typeprof/core/graph/box.rb:151:in `each'
```
This is because the SigTyIntersectionNode class does not have an initialize method, and the `@types` instance is not initialized.
This commit fixes it.
