Display browsable layout for http/s scheme intents

Displays Settings button instead of always button for all intents that
have http or https scheme, as opposed to only intents that have
BROWSABLE as category.
This fixes an inconsistent and confusing behaviour that users were
experiencing, as sometimes they saw the Always button and sometime the
Settings button.

Test: open a mail.google.com from Facebook Messenger - used to display
Always button and now displays Settings button
Test: use shell command to send https intent without BROWSABLE category
- used to display Always button and now displays Settings button
