Fix panic on close last buffer (#2367) (#2658)
* Fix panic on close last buffer (#2367)
In certain circumstances it was possible to cause a panic when closing
buffers due to some mishandling of view document history.
A change has been made to delete removed documents from the history of
accessed documents for each view. The ensures we don't attempt to jump
to a deleted document by mistake.
* Move remove document code into View function 'remove_document'
* Replace 'view.jumps.remove' call with 'view.remove_document' call
