[XFA] Force destruction order of font managers.chromium/2838
The GEFont points to the font manager which creates it and tries to unregister
itself. Currently the GEFont can be created by the default mapper and then
stored in a different mapper. If the default mapper is destroyed first, when
the second mapper cleans up the font there will be a call to unregister on
the default mapper causing a use-after-free.
The long term fix is to fixup the GEFont so it points to the correct mapper
to unregister from. This CL forces the destruction order in CXFA_FFApp to
cleanup the non-default mapper first.
