ERP5Type.mixin.component: Avoid acquiring workflow_history.

workflow_history attribute may not exist on bootstrapping (constructInstance),
which could lead to acquisition, which could have further side-effects
as this is called during dynamic class initialisation.
Also, original code from CMFCore.WorkflowTool, from which this code is
derived for bootstrap reasons, does the equivalent aq_base, so follow
the same pattern.
