ProjectExplorer: Fixup aspectized MakeStep

Browse Source 
- Postpone OverrideMakeflag label creation until it is needed.
  This also fixes a leak as in the un-shown case when it never got a parent.

- Use the widget as guard object in update connections. The widget (and the
  aspects' widgets parented to it) gets destroyed e.g. when the active build
  configuration is switched.

- For extra snake oil, put the step widget in a QPointer in updateDetail.

Fixes: QTCREATORBUG-24469
