Only show any expr errors from resultant expressions, not intermediate expressions

```py
a: list[Any] = []
a.clear() # expect no error
a # expect error
```

Start by locating the type-checking path for the `list[Any]` example, especially how `a.clear()` and the standalone `a` expression are analyzed. Confirm the current diagnostics, then make the behavior match the stated expectations: no error for the intermediate method call and an error for the resultant expression.
