This makes the tokens not expire when such errors happen.
Only applies to MSA, not the XBox and Mojang steps afterwards.
Further testing and improvements are still needed.
- We now use the new endpoint for loggiong in via XBox tokens (/launcher/login)
- We now check game entitlements instead of only relying on MC profile presence
- Accounts can now be added even when they do not have a profile
- The launcher will guide you through selecting a Minecraft name if you don't have one yet
