Error appears for projects where terminals.json is not defined

[anpale]

if ( !terminals.length ) vscode.window.showErrorMessage ( 'No terminals defined, edit the configuration' );

This error should only prompt when a terminals.json file is present in the .vscode directory. For projects without this file, where terminals is not required the error should not be displayed. Currently, however, the error appears for every project. Additionally, there is no option to disable this error, making it inconvenient for users.
