[FIX] web: MEASURES button disappearing when switching back to graph

before this commit, when change view from graph view to pivot view or any other
view and come back to graph view, Measures button disappear, it's only
appearing if we refresh the page.

after this commit, restore previous view state when switching back to graph
view, this was because measures button is rendered in fragment and when
switching between views, as graph view element was destroyed and re-rendered
so measures button will be mounted in fragment as update method of
ComponentWrapper will render it from previous mountArgs, so to avoid this issue
push measures element in DOM.
