Popup not showing in iOS 13

[cjfradley]

The popup doesn't seem to be showing in iOS 13
When calling authenticate on TiIdentity the popup doesn't show.
The module still reacts to fingerprints and recognises them and also sends the success callback, so the functionality is still given.
The popup is shown shortly after the fingerprint is given but is not visible beforehand.

iPad (6th generation)
I have tried on iOS 13.1 and on iOS 13.1.2
Using ti.identity version 1.0.6
