[Files app] Clicking both "Done" buttons at folder creation breaks the Files app

[michaelstingl]

Steps to reproduce

1. Perform steps from #203 in iOS Files app
2. Tap the "New folder" button and enter name "Test"
3. Tap bottom-right "Done" button ==> Keyboard disappears, but no other immediate response
4. Tap bottom-top "Done" button (don't wait too long) ==> Error message "The name "Test" is already taken. Please choose a different name" appears and disappears automatically, then the Files app is stuck. Top-left "Cancel" button doesn't work. Only force-quitting the app helps.

Step 2.	Step 3.	Step 4.
Stuck	Force-quit	Network Link Conditioner

Using Network Link Conditioner might help to simulate slow network.

In other tests I was a little slower, then a zombie folder remained. Sadly, I never captures this with logging enabled.

Expected behaviour

Double-input should be prevented. First action needs to be finished before another action can be started.

Actual behaviour

Files app is stuck. Top-left "Cancel" button doesn't work. Only force-quitting the app helps.

Not reproducible on my side. @michaelstingl do you still reproduce it?

@michaelstingl do you still reproduce it?

Yes, but I don't have the latest-latest version. I'll try again with the nextTestFlight and provide feedback.

Yepp, I still can reproduce with ownCloud beta version 1.0 build 103 (https://github.com/owncloud/ios-app/commit/373776c5dbf0b508e9b369972b7601b0409f0049)

I noticed the error message got uglier:
