Signs with click event dont serialize properly

[SB2DD]

Describe the issue
When having signs with a click_event on a slime world, restarting the server will make the sign be fully blank.

On world start, you can even see the following error:

minecraft:sign // net.minecraft.world.level.block.entity.SignBlockEntity@BlockPos{x=0, y=62, z=-3}: Failed to decode value '{color:"black",has_glowing_text:0b,messages:[{click_event:{action:"run_command",command:"say e"},text:"asdasdasdas"},{"":""},{"":""},{"":""}]}' from field 'front_text': Failed to parse either. First: Failed to parse either. First: Not a string; Second: Not a list: {"":""}; Second: No matching codec found; Failed to parse either. First: Failed to parse either. First: Not a string; Second: Not a list: {"":""}; Second: No matching codec found; Failed to parse either. First: Failed to parse either. First: Not a string; Second: Not a list: {"":""}; Second: No matching codec found; Input is not a list of 4 elements

This error therefore makes me believe this is a serialization issue somehow.

Can you try it with the newest develop build? It should be fixed now
