Revert "Respect global toolbar style for page in layers"
This reverts commit d4f43846.
Skipping (globalToolBar.row && ...) check in the alternative code pass causes null dereference on the next line:
file:///usr/local/kde/usr/lib/qml/org/kde/kirigami/Page.qml:139: TypeError: Cannot read property 'globalToolBar' of null
Sorry I'm not trying to fix the MR for you, because there were no test plan or unit tests
