Fix blank buffer picker preview on doc with no views

Browse source 
Reproduction:

* `hx`
* Open any file in a split (`<space>f` and choose anything with `<C-v>`)
* Close the split with `<C-w>q`
* Open up the buffer picker and look the file you opened previously

Previously the preview was empty in this case because the Document's
`selections` hashmap was empty and we returned early, giving `None`
instead of a FileLocation. Instead when the Document is not currently
open in any view we can show the document but with no range highlighted.
