Login app redirect from within Telegram WebApps on Android not working

[aorumbayev]

Issue description

Upon clicking login when invoked from within Telegram native WebApps in a bot, authentication redirect into pera wallet app is not working.

Same behavior works fine on iOS and Desktop telegram clients.

Steps to replicate

1. Open https://t.me/algoworld_swapper_bot from within telegram
2. Open webapp inside the bot
3. Click login
4. Select pera
5. Observe popup being loaded and click to authenticate
6. Observe error (redirect does not happen and app is stuck)

Expected behaviour

Redirect invokes pera android app

Further notes

I suspect it has something to do with the fact that its invoked from within telegram and webapp does not have access to parent filesystem (can't issue redirect). Not sure why this works fine on ios though, probably because its a different acl in ios.
