Update currentlyOpenBlock on block delete

[firzanarmani]

Closes #354

Fixes currentlyOpenBlock not updating when the currentlyOpenBlock is delete by using a RelativePath with delete .

currentlyOpenBlock will now change to its the deleted block's parent upon successful deletion.

EDIT: ~- Deleting some distant block from currentlyOpenBlock will still open to that distant block's parent~

• currentlyOpenBlock changes if the currentlyOpenBlock does not exist due to the deletion of itself or one of its predecessors. It will change to the first available predecessor i.e the parent of the block deleted.

@firzanarmani Hey Firzan, this doesn't seem to be working. I screen recorded the problem I encountered below.

You can try out the sequence above. In my place, the whole app crashes as that command was executed.

Missed out something, thanks for picking it out @kevinputera

What do you think about this?
