Michael Natterer c110220793 Bug 693978 - GIMP crashes after changing text preset 
Applying a preset overwrites all the tool option's properties, also
temporarily its name. This name change gets auto-synced with the
option's text proxy object which also inherits from GimpObject and has
a name. Make sure we don't queue that name change for being applied to
the text layer's text object, because that code only handles
properties of GimpText itself.
