QmlJSEditor: Automatic indentation breaks after user handles quotes wrong

Steps to reproduce:

• if it matters: I'm using clean settings
• create Quick Application - Empty from template
• inside the Window element
  • add a Text element
    • add property text and give it some string value, but hit Enter with having the text cursor still before the closing quote
    • use Backspace to return to the line before
    • use End or CursorRight to move behind the closing quote and hit Enter again (places cursor already wrong at the begin of the line)
    • add another property or item inside the Text element or anywhere else where it would be valid

Current result: indentation is now broken for the whole document if you try to use indent line (Ctrl+I).

Note: Using Ctrl+A and Ctrl+I still works.
