[Sprint/ModestMonkey](feat): Added in pending boost limit for #591
The simplest way is going to be to log in as admin, then open 2 windows.
Next, make posts numbered 1, 2, 3 and 4 on the newsfeed, and boost them.
On 4, you should receive an error indicating that you have exceeded the pending boost limit.
After this, go to the other window (admin panel), refresh, and approve a boost. Try the boost 4 again, it should let you.
Try approve all, and do 3 fresh boosts.
