Issues updating to latest develop

Hi ,

I updated my production node to the latest develop this morning and I encountered two problems:

• No styles were loaded (as others have been reporting). I found out that the value of system.url in config/node.config.php had changed to http://friendica.mrpetovan.com (notice the absence of https) which triggered mixed content errors in my browser, preventing from loading the styles. Updating the config value to https://friendica.mrpetovan.com fixed the issue. Still, it shouldn't have happened in the first place.
• Session didn't work across page loads. I use the Cache session handler with the Memcached driver, the session_id was constant across pages, the session handler methods were called, but ultimately no data was retrieved. Running out of ideas to troubleshoot this critical issue, I reverted to stable where session worked again instantly.
