Can't Grant Badge - Generic Error

[saurabhp (Saurabh Patel)]

Change to send an error from backend if the reason was not valid was done here:

Hi @dax , I have created PR for the same. I just wanted to confirm only links have to be allowed in reason, right? Plain text is also not valid, right? https://github.com/discourse/discourse/pull/6690 Thanks

I have made the change to show the corresponding message to the user here. This needs to be reviewed:

FIX: show error msg on grant badge if message available from backend
