Reactions plugin: 500 Internal Server Error

[Don]

Ok finally I think I have a clean repro for this: I think this is happens when the user has reaction in one of the not deleted post in a deleted topic (OP).

Repro:

1. Add reaction to OP and the second post.
   

   

2. Check the Test1 user activity/reactions page it works now as expected
   

   

3. Delete only the topic OP with delete topic button so the second post not deleted.
   

   

4. Check the Test1 user activity/reactions page again drop a 500 error because I think the route is broken.
   

   

5. Un-Delete the topic or delete the post too will recover the activity/reactions page.

It also happens with deleted category if the About the … category topic has reactions. I think because the actual post not deleted.

1. Add a reaction with Test1 user in the Test Subcategory category.
   

   

2. Check the Test1 user activity/reactions page works as expexted
   

   

3. Delete Test Subcategory category.

4. Check the Test1 user activity/reactions page again will drop a 500 error because the reaction left on the OP and the route is broken.
