[FIX] web_editor: commit changes when using the sidebar

Before this commit, some operation (eg. move node, duplicate or remove a
snippet from the snippetMenu) in the snippetMenu sidebar did not
trigger the mass mailing commit changes and therefore if no selection
was made in the document followed by a blur was made, no changes could
be recorded and saved by the owl form component.
