5.4 DEV build 1678 RC2

More bugfixes to build 1661. This is a release candidate.

Changes from dev build 1661

Fixed user_id reference error on MariaDB (Error codes for not null constraint were different and thus not detected correctly)
Fixed user_id reference error related to ServerShutdownPreservation
Fixed parsing error related to server shutdown preservation csv file
Fixed typo in RemoveDanglingServerDataPatch that caused it to fail
Fixed 2 crashes when database write latency is high
- Fixed thread starvation crash during high latency when using ViaVersion or ProtocolSupport
- Reduced chance of out of memory crash when database during high latency by starting to drop plugin data transactions for a while if queue grows over 500 transactions. (The transactions continue if queue returns to <50)
Fixed issue where Plan would prevent server enable from continuing if database was not responsive during enable.
Fixed Cookies not getting removed from database in some cases when expired.

Implemented player ping graph on the player page when opted into frontend beta
Fixed nickname list not showing colors properly
Fixed terminal icon not loading when user registered with console
Fallback to using relative address if Alternative_IP is misconfigured to reduce confusion. Previously nothing would load if address was different, now there's a chance something loads.

Join addresses are now stored in plan_join_address table and id referencing that is added to plan_sessions table for time based analysis implementation later.
- Backwards compatible schema change - old versions will insert 'unknown' as each sessions address.
- plan_user_info.join_address column was not removed, but its use is discouraged for 3rd parties as its use may be removed in the future.

Fixed thread starvation crash during high latency when using ViaVersion or ProtocolSupport
Reduced chance of out of memory crash when database during high latency by starting to drop plugin data transactions for a while if queue grows over 500 transactions. (The transactions continue if queue returns to <50)

Fixed issue where Plan would prevent server enable from continuing if database was not responsive during enable.
Prevented transactions from executing if database ran into fatal error. This reduces amount of errors logged on a failed patch
Fixed error related to user_id constraint violation for Ping and Session store transactions. If they execute faster than the user register transaction the player will not have up-to-date information until the proper transaction executes, but the storage of other data will no longer fail.
Prevented ActiveCookieStore related DbOpException if plugin failed to enable
