nvim: Improve snippet jumping

Browse source 
Snippets can be jumped through more easily now since jumping between
snippets (with <tab> and <s-tab>) takes precedence over completions and
jumping through completions. That means when a snippet has been expanded
we can now cycle through its insertion points without worrying about
activating completion items instead.

Additionally, only jump through insertion points as long as we are
within the snippet boundaries with the cursor, so it doesn't surprise
jump later when pressing <tab> from somewhere else in the file.
