MultilineArrayTrailingCommaFixer - do not move array end to new line

Currently
```php
<?php
    $var = array(
        "string",
        /* foo */);
```

is changed:
```diff
 <?php
     $var = array(
-        "string"
-        /* foo */);
+        "string",
+        /* foo */ 
+);
```
First, this fixer is not supposed to move end of array, and next, the end of array is wrongly placed (no indent)

The fixer should only add a comma, like:
```diff
 <?php
     $var = array(
-        "string"
+        "string",
         /* foo */);
```
