[Bug]: Slither fails analysing `raw_call` to `empty(address)`

### Describe the issue:

Slither crashes when given a Vyper contract containing a `raw_call` to `empty(address)`

### Code example to reproduce the issue:

```Vyper
@external
def foo():
raw_call(empty(address),b'')
```

### Version:

`0.10.0`

### Relevant log output:

```shell
