Launch configurations are not available for running

[RomanNikitenko]

Bug Description:

I faced with the issue that under certain conditions launch configurations are not available for running from Debug panel - they are not displayed in the list.

The first use case is: user has some debug configurations defined in

• someProject/.theia/launch.json file
• workspace config file, for example theia.theia-workspace file - so workspace launch configurations

The current behavior:

• the configurations from someProject/.theia/launch.json file are available for running
• the configurations from theia.theia-workspace file are NOT available for running

The second use case is: user has some debug configurations defined in

• someProject/.theia/launch.json file
• someProject/.vscode/launch.json file

The current behavior: configurations from someProject/.theia/launch.json file only are available for running.

About second use case I'm not sure - maybe it's expected behavior and user should keep launch configurations either .vscode/launch.json either .theia/launch.json file.
But workspace configurations should be available for running and don't depend on existence of configs in .theia/launch.json file

Steps to Reproduce:

1. Start a multi-root workspace from config file with launch configurations (please see the example below )
2. Add another launch configuration to yourProject/.theia/launch.json file
3. Go to the Debug panel and check if the workspace level configs are available for running
4. Remove yourProject/.theia/launch.json file
5. Go to the Debug panel and check again if the workspace level configs are available for running

Example of workspace config file with launch configurations:

{
    "folders": [
        {
            "path": "theia"
        },
        {
            "path": "vscode"
        }
    ],
    "settings": {
        "launch": {
            "configurations": [
                {
                    "name": "Launch Chrome",
                    "request": "launch",
                    "type": "pwa-chrome",
                    "url": "http://localhost:8080",
                    "webRoot": "${workspaceFolder}"
                }
            ]
        }
    }
}
