Error during migrate_3_to_4 v4_0/global_defaults_to_system_settings.py results in get_lang_dict()[la

[Jev Björsell]

Hi all,

I just filed a bug against frappe-bench relating to a language key error that happens during the migrate_3_to_4 procedure;

Bug is here:

https://github.com/frappe/frappe-bench/issues/16

Any suggestions on a quick work around would be greatly appreciated.

Thanks,
