Saving players with keepInventory enabled on death saves a state where a player has an empty inventory as #getDrops returns an empty list

[emmanuelvlad]

Issue:

When a player dies with keepInventory enabled (event.getKeepInventory), it saves an empty inventory because #getDrops is empty.

Usecase:

Using a dynamic keepInventory in certain worlds/regions and need to save players inventory on death if keepInventory is disabled

Proposed solutions:

1. Do not save on death if the player has keepInventory enabled.
   | This is a quick fix but will not support custom half-keepinv where only some items drop
2. Save player's inventory and drops only if drops are not empty
   | Supports custom half-keepinv and saves only if there are drops, else do not create useless snapshot
