Fix ignored OrdersUITest

[irfano]

Description

OrdersUITest was ignored during toolbar refactoring process. Some parts of the order-related tests were addressed in #12906. This PR resolves the remaining issues with OrdersUITest.

Before, OrdersUITest was failing with the following error:

 androidx.test.espresso.AmbiguousViewMatcherException: 'view.getId() is <2131364783/com.woocommerce.android.dev:id/toolbar>' matches 2 views in the hierarchy:
- [1] MaterialToolbar{id=2131364783, res-name=toolbar, visibility=VISIBLE, width=1069, height=154, has-focus=false, has-focusable=false, has-window-focus=true, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, layout-params=com.google.android.material.appbar.CollapsingToolbarLayout$LayoutParams@YYYYYY, tag=null, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=-154.0, child-count=3}
- [2] MaterialToolbar{id=2131364783, res-name=toolbar, visibility=VISIBLE, width=1080, height=154, has-focus=false, has-focusable=false, has-window-focus=true, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, layout-params=android.widget.LinearLayout$LayoutParams@YYYYYY, tag=null, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=3}

This error was caused by duplicate toolbars on the screen. I'm not sure if this is optimal or not, but it falls outside the scope of this PR. To resolve the AmbiguousViewMatcherException, I used the first found toolbar to assert the toolbar title.

Steps to reproduce

Test OrdersUITest.
