Learning direction dialogue has stuck locale identifiers

[licaon-kter]

Have multple languages eg. know English want French, and know Spanish want English, so the interface is changed (this is a bad UX decision in Duolingo but whatever) each time you change what you want to learn.

Leave it with French...

• swipe Duolingo to close it
• load this app and login
• see that starting cards have EN->FR and FR->EN as expected
• See that you can't change to Spanish from this app
• Close this app
• Open Duolingo
• Change to Spanish
• swipe Duolingo to close it
• load this app
• see that starting cards have STILL EN->FR and FR->EN text in the dialogue, but the cards are ok in Spanish once running
• Clear Data for this app
• load this app and login
• see that starting cards have EN->ES and ES->EN as expected
• Change them more while testing for this issue only to have them mixed up as ES->FR and FR->ES (!?)
