[BUG] Unused import when chained imports

├───__init__.py
├───module_1.py
├───module_2.py

__init__.py
```python
A = 1
```

module_1.py
```python
from some_package import A
```

module_2.py
```python
from module_1 import A

print(A)
```
 

`Optimize Imports` will remove `from some_package import A` and make `module_2.py` fail
