[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.
