PERMISSION FORM: Catch failed host lookup

[gjwgit]

Describe the Bug

As a user if I enter an invalid webID (e.g., invalid host) the tapping SELECT WEBID simply does nothing 👎

I have no idea (except looking at the console) what is going on.

To Reproduce

Steps to reproduce the behavior:

1. Open NOTEPOD
2. Select a note
3. Tap SHARE
4. Tap SHARE RESOURCE
5. Tap INDIVIDUAL
6. Enter https://pod/a/profile/card#me
7. Tap SELECT WEBID
8. Review the console error message

Expected Behaviour

A popup to tell me what is going on - Failed host lookup: 'pod'

Fixed. Also fixed the bugs in some other scenarios.

Correct WebID (e.g. https://solid.dev.empwr.au/intony/profile/card#me) (HTTP 200 + text/turtle)

Domain name cannot be resolved (e.g. https://solid.dev.empwr/intony/profile/card#me)

WebID does not exist (e.g. https://solid.dev.empwr.au/intony2/profile/card#me)

⚠️ Some invalid WedID can be accepted mistakenly (e.g. https://www.cn2.com/intony/profile/card#me) (HTTP 200 but returns HTML)

Invalid WebID with IP address (e.g. https://127.0.0.1/intony/profile/card#me)

Invalid WebID with incorrect IP address (e.g. https://127.0.0/intony/profile/card#me)

Invalid WebID with special characters address (e.g. https://solid.dev.empwr。au/intony/profile/card#me)

Thanks @tonypioneer. Great information/feedback to the user.

Can we limit the width of the popups to be 100 chars (roughly).

Thanks.
