Read-only scoreboard objectives only initialize when respective value is changed

The bug

Read-only scoreboard objectives are only initialized when the value they are tracking changes. Expected would be that they initialize on creation.

Affected objective criteria

• air
• armor
• food
• health
• level
• xp

How to reproduce

1. Create a scoreboard objective of the type xp

   /scoreboard objectives add xp xp
   

2. Check if a value is set by displaying the objective on the sidebar or trying to get the score

   /scoreboard objectives setdisplay sidebar xp
   

   /scoreboard players get @s xp
   

   → No value is set

3. Update your xp points

   /xp add @s 1
   

4. Repeat step 2
   → Now a value is set
