Fix "Fix Imports" issue with declare statements apache#5578

- apache#5578

Example:
```php
<?php
namespace NS1;

declare(ticks=1) {
    $test = 1;
}
declare(ticks=2) {
    $test = 1;
}
class DeclareTest1 {
    public function test() {
        declare(ticks=2) {

        }
        $test = new \NS2\DeclareTest2;
    }
}
```

Before:
```php
<?php
namespace NS1;

declare(ticks=1) {
    $test = 1;
}
use NS2\DeclareTest2;
declare(ticks=2) {
    $test = 1;
}
class DeclareTest1 {
    public function test() {
        declare(ticks=2) {

        }
        $test = new DeclareTest2;
    }
}
```

After:
```php
<?php
namespace NS1;

declare(ticks=1) {
    $test = 1;
}
declare(ticks=2) {
    $test = 1;
}

use NS2\DeclareTest2;

class DeclareTest1 {
    public function test() {
        declare(ticks=2) {

        }
        $test = new DeclareTest2;
    }
}
```
