Ignore system colour change events in not yet initialized wxPropertyGrid.
Handling these events before the initialization was over could result in a crash because m_categoryDefaultCell wasn't yet initialized when the window was created. Fix this by ignoring these events during initialization. Closes #15642. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/branches/WX_3_0_BRANCH@75128 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
