Currently if an item doesn't have any statements in place, it's not possible to add a statement and see newly added statement after saving it without reloading the page.

It's something I figured out while working on T405454, it needs bigger changes therefore a new ticket would be better.

Currently every StatementGroupView is an individual Vue component, therefore if a new one is to be added, a new root component should be initialized. Instead of this, we can wrap those StatementGroupView components with one wrapper component, therefore we can add a new one easily within Vue.js.

AC:

• After submitting a new statement to an item with no statements on mobile view, added statement is shown on the screen without page reload/refresh.
