Import after use gets removed

With 0.7.4 and --remove --include-star-import --ignore-init --gitignore

In code like this

def bob():
    print(sys.path)

import sys

The import gets incorrectly removed.

You might reasonably ask why I even had code like this, in larger files my work flow is to just drop imports in the nearest bit of module level scope and let unimport and isort clean it up.

Unimport is currently using primary analysis methods, this problem will be solved if scope analysis is added.
