Adding an identical existing checkpoint should not error

Browse Source 
For checkpoints being read at runtime to work correctly, the checkpoint
add code needs to not return false if a checkpoint is added that already
exists.  In this case, instead return false if the checkpoint is for a
height that already has a checkpoint and the hashes are different.
