"group leave" button sometimes not available

[r10s]

see https://support.delta.chat/t/to-leave-from-a-group-on-ios-app/761/6

the current master shows the button on my device, however, maybe there is also some bug, some weird condition or so, we should check that over.

Let me emphasize this, for me always I can’t see the leave button to exit from all the groups.

Looks like it's hidden when currentUser is nil.

thanks for the hint!

in fact, there was such a condition for some reason at

deltachat-ios/deltachat-ios/Controller/GroupChatDetailViewController.swift

Line 127 in 53021a5

if currentUser == nil {

- however, due to the last refactorings, the "leave" button is shown unconditionally, so i think this bug is fixed.
