52962db24c Adjusted Closure methods signatures 
This fixes the following false-positive:
```php
function a(): bool {
  $a = function(): bool { return true; }
  return $a->call(new stdClass);
}
```
where psalm previously complained about (wrongly) inferred type to be

f080e32ef0 Corrected case of Traversable typehints 
Affected functions/methods:
* `iterator_apply()`
* `iterator_count()`
* `IteratorIterator::__construct()`
* `iterator_to_array()`

This fixes the following false-positive:
```php
class Iter extends IteratorIterator {
    public function __construct(Traversable $a) {
	parent::__construct($a);
    }
}
```
where psalm previously wanted `parent::__construct()` argument to be
`traversable` (all-lowercase).
