]Link.Status crashes if a Linked folder got removed

**Describe the bug**

Removing a folder which was Linked with a namespace with `-watch=ns` makes `]Link.Status` errors with

```
ERRORS ENCOUNTERED: FILE NAME ERROR: /path/ Unable to read directory status
```

**To Reproduce**

```
]LinK.Create Foo /path/to/folder -watch=ns
⎕sh 'rmdir /s /q /path/to/folder
]Link.Status
```

**Expected behaviour**

Should report a broken link instead.

I am on Link 3.1.1
