Treesitter on empty window

[David Brouwer]

Small error, when calling the treesitter searcher on an empty buffer I get this;

E5108: Error executing lua: .../packer/start/navigator.lua/lua/navigator/treesitter.lua:770: attempt to perform arithmetic on local 'width' (a nil value)                                          
stack traceback:
        .../packer/start/navigator.lua/lua/navigator/treesitter.lua:770: in function <.../packer/start/navigator.lua/lua/navigator/treesitter.lua:759>

I guess it should just fail silently or print a msg that there's nothing to run

should be fixed.
