Jules Aguillon 4629410230 Fix unintended layout used for unsupported languages
The arabic layout was used as the default on devices where all the
installed languages are not supported by the keyboard. This is not
intended.
This is probably caused by 'getCurrentInputMethodSubtype' returning the
first layout in the list of disabled subtypes in alphabetical or
language tag order.
Re-ordering the subtypes in method.xml had no effect.

Setting 'overridesImplicitlyEnabledSubtype' in method.xml has no
measured effect.
