Aikar fc271fbed3 Restore some SANITY around nullability annotations
Some of these were wrong (scoreboard manager), others are counter to
everything everyone expects (Locations world being null, which wasnt ever safe EVER)
others are just too noisy.

Replace some with Contract to get rid of the nullability constraint and go back to
the old days of IDE not considering it strictly one way or the other.

Also, stop requiring annotations on package-private.

Introduces the next Developer Perk for Paper-API: Your plugin isn't yellow anymore.

Also fixed random dupe code in ensureServerConversions that got mistakenly set in the update.

Subject: [PATCH] Flip some Spigot API null annotations
while some of these may of been true, they are extreme cases and cause
a ton of noise to plugin developers.
These do not help plugin developers if they bring moise noise than value.
