Old project name present in Project Outline after project was renamed

[Zingam]

Type: Bug

I changed the name of my CMake project (including some additional changes). Sometime later I noticed that in the Project Outline both the new and the old project names were available.
After I restarted VSCode only the new name was present.
This seems to be a bug.

@Zingam @gcampbell-msft I reproduced this issue as described by the user, but after I reconfigured the project, the changes made could be displayed correctly in the project outline view, which I think should be the cache that needs to be regenerated after the changes have been made.
ENV:
ENV:
VS code version: 1.90.0
CMake Extension version: 1.18.42

Steps to reproduce:

1. Create a folder named Test and open it with vscode.
2. Add the CMakeLists.txt file and add the following code:

cmake_minimum_required(VERSION 3.8)
project(test)
add_executable(test main.cpp) 

3. Add the main.cpp file and add the following code:

#include <iostream> 
      auto main() -> int { std::cout << "hello world" << std::endl; }

4. Change the name of main.cpp to main1.cpp
5. Open the project outline view

Actual Result:

@v-frankwang
Please also try chaning: project(test) to something else project(test-renamed). You should get something like:

Please note the duplicated entries on the left. Delete Caches and Reconfigure doesn't fix it. After restarting the project:

@H-G-Hristov @gcampbell-msft Based on the information provided by the user, I reproduced the issue and here are the steps to reproduce it:

repro steps：

1. Create a folder called demos and open it with vscode.
2. Add the CMakeLists.txt file and add the following code:

cmake_minimum_required(VERSION 3.8)
project(demo)
add_executable(demo main.cpp)

3. Add the main.cpp file and add the following code:

#include <iostream> 
      auto main() -> int { std::cout << "hello world" << std::endl; }

4.Add the following code to the CMakeLists.txt file:

set(PROJECT_NAME "newdemo")
project(${PROJECT_NAME})

5. Run command:"CMake：Delete Cache and Reconfigure"
6. Click on the CMake button in the left navigation bar to observe the PROJECT OUTLINE window
