Create a block, e.g. test1
Then delete the block, the block list is empty
Create a new block test1 again, LC says that a block with name test1 already exists
this behavior is by design. in order to enable "undo" for block deletion, a deleted block is not removed from storage, only labelled as "deleted", therefore, creating a new block with the same name is not possible.
there's no easy solution here. We can delete this block permenantly, whenever user requests a new block with the same name, but it's not perfect either.

if user requests a new block name which is taken by a deleted block, we can silently rename the deleted block.
