fixed removal of imports that appears after a comment in the imports

When there are imports after a comment in the imports block, they get removed so for example:
```python
import re
# some random comment
import sys

def main():
    print(sys.path)
    print(os.uname())
```
Get translated to
```python
import os
import sys

def main():
    print(sys.path)
    print(os.uname())
```

This commit fixes this behavior but the comment is still gone
