WebView is never enabled if final request is NSURLErrorDomain error -999

[crswlls]

Version

• component version = 1.6.0.3

Steps to reproduce

User attempts to authenticate and page resources are loaded:

1. Final resource is loaded by the auth page
2. WebView gets disabled during load (UIWebViewDelegate LoadStarted)
3. resource request is cancelled for whatever reason (NSURLErrorDomain error -999)
4. UIWebViewDelegate LoadFailed method returns early
5. webView.UserInteractionEnabled = true never happens
6. WebView remains disabled and there are no further requests to enable it

Platform:
iOS

Expected behaviour

Just as with other errors, UIWebViewDelegate should re-enable user interaction even if controller.authenticator.OnError is suppressed (as it seems was the initial intention of #41)

Actual behaviour

WebView interaction remains disabled
