Rename symbol fails with assert statements

[ehatton]

Environment data

• VS Code version: 1.45.1
• Extension version (available under the Extensions sidebar): 2020.5.80290
• OS and version: Windows_NT x64 10.0.18363
• Python version (& distribution if applicable, e.g. Anaconda): 3.8.2 Anaconda
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): conda
• Relevant/affected Python packages and their versions: n/a
• Relevant/affected Python-related VS Code extensions and their versions: n/a
• Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info How to update the language server to the latest stable version vscode-python#3977): Language Server
• Value of the python.languageServer setting: Microsoft

Steps to reproduce:

1. Create a file containing the following code in a new project directory:

class Foo:
    def __init__(self):
        self.foo = "test"


f = Foo()
assert f.foo == "test"
print(f.foo)

2. Wait for python extension to finish loading.
3. Put cursor on the foo attribute in line 3 and press F2, rename symbol to "bar".

Expected behaviour

The foo attribute is renamed on lines 3, 7 and 8.

Actual behaviour

The foo attribute is only renamed on lines 3 and 8, but not in the assert statement on line 7, see screenshot below:

I noticed this bug while trying to refactor some code which uses pytest for testing (hence lots of assert statements). It seems to only affect class attributes and not variables.
