Fix incorrectly tagging release crashes as staging
- will now upload crashes as "unknown" branch if they are untagged (aka old crashes) instead of tagging everything as staging
- remove "release" tag that was passed through code, instead put the release / staging tag directly into the crash marker
- fix failing to parse for the crash marker if timestamps are enabled in the logs
- output crash marker earlier so early crashes can still be tagged correctly
- fix userid / steamid not being set early enough either
