"Rename Symbol (F2)" inserts blank lines

[srechenb]

Type: Bug

Using the "Rename Symbol (F2)" function also replaces every /n character with /n/n, thus adding unnecessary blank line severy time this function is used.

Create a new Python file in VS code, write some lines of code, and save. After auto-formatting, the code looks like this:

import pandas as pd

data = pd.Series([0, 0, 1, 0, 2, 0, 1, 2, 3, 7, 0, 0])
first_non_zero = data.ne(0).idxmax()
last_non_zero = data[::-1].ne(0).idxmax() + 1
trimmed_data = data.iloc[first_non_zero:last_non_zero]

Use Rename (F2) to change "first_non-zero" to "first_ind". The resulting code looks like this:

import pandas as pd


data = pd.Series([0, 0, 1, 0, 2, 0, 1, 2, 3, 7, 0, 0])

first_ind = data.ne(0).idxmax()

last_non_zero = data[::-1].ne(0).idxmax() + 1

trimmed_data = data.iloc[first_ind:last_non_zero]

Auto-formatting doesn't remove these extra lines. This behaviour is unexpected and inconsistent with earlier version of VS Code.

This seems to only occur when using jedi as the language server, and it looks like they already have an issue for it pappasam/jedi-language-server#159
