Removing a post reaction after that reaction was removed from settings throws an error

[Arkshine]

Steps to reproduce:

• Add a reaction to a post, for example
• Remove from the allowed list in the admin
• Try to remove that reaction to the post
  • An error is thrown.

I’ve done something similar to this before, and changing the reaction before removing it lets it be removed normally.
