[BUG] VsCode Tabbing #14

Describe the bug The tabbing in the vscode extension is just wrong.

To Reproduce

1. install Backstention
2. type a function call like print() inside a func like main (will remove all tabs from the line) (FIRST TAB ISSUE)
3. hit enter and the cursor will get one level higher (SECOND TAB ISSUE)

Expected behavior Normal Tabbing like without the extension
