This reverts commit 7c911eca96.

I'm dumb. We need global mode because otherwise lastIndex is not updated in the
regex object, which we rely upon, so this is intentional.

The URL cannot end in a /.

e729f0948c contained an off-by-one error:

URI_PROTOCOL_PATTERN includes the colon, so after applyting the regex we are
left with something like '//example.com/room' thus we only need to strip the
first 2 characters.

🤦

Looks like custom-scheme links no longer work in all browsers. They do on
Firefox, but the don't in Chrome and other default browsers.

So, switch to intent links on Android:
https://developer.chrome.com/multidevice/android/intents

Example:
```
<a href="intent://meet.jit.si/test123#Intent;scheme=org.jitsi.meet;package=org.jitsi.meet;end">Open Jitsi Meet</a>
```
