Wrong file referenced in Find/List All References and Rename Symbol #454

Environment data

• VS Code version: 1.29.1
• Language server version: 0.1.65.0
• OS and version: Win 10 x64
• Python version (& distribution if applicable, e.g. Anaconda): Anaconda 3.7.1 x64
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): conda
• "python.jediEnabled": false

Steps to reproduce:

• Create 2 files:

# foo.py

from bar import baz


class spam:
    __bug__ = 0


def eggs(ham: spam):
    return baz(ham.__bug__)

# bar.py

# comments ########################################
# more commments ##################################
# even more comments ##############################


def baz(quux):
    pass

• Hover over __bug__ and Find All References
• Completely unrelated file bar.py is referenced at offset 112 which is exactly the offset of __bug__ in foo.py at line 11
  
• List All References behavior is identical
• Trying to rename F2 __bug__ to some_random_variable works fine for foo.py but changes bar.py:

# bar.py

# comments ########################################
# more commments ##############################some_random_variable even more comments ##############################


def baz(quux):
    pass
