[BUGFIX] Do not open EditDocumentController in modal

If `mod.web_layout.disableNewContentElementWizard=1` is set, the
"New Content Element" wizard is skipped and EditDocumentController's
FormEngine is called directly.

In that case, the modal must not get opened as this doesn't work in
combination with FormEngine.
