[IMP] prevent import error diagnostic in ImportError catch clause of try..catch

If a missing impotr is in a catch clause like
```python
try:
    pass
except ImportError:
    import something_wrong
```
we should not raise a diagnostic as the content of the try will probably contain the right import
