Before this commit, multiple toolbar instances would be created when switching between records via the form view pager. This commit fixes the issue by using and properly setting up the existing Toolbar child component, without the need to instantiate a new one. It also removes this module's dependency on the legacy ComponentWrapper. task-3495685 closes odoo/odoo#144802 Signed-off-by: Nicolas Bayet (nby) <nby@odoo.com>
