fix: check if bufdata.last_win != nil (#356)

Browse source 
When opening nvim in diffview (`nvim -c DiffviewOpen`) and then toggeling aerial,
aerial errors when trying to call `vim.api.nvim_win_is_valid(bufdata.last_win)`
as bufdata.last_win == nil. This change adds a check and returns in case of a nil
value.
