Fix using double-quotes in VimspectorEval

The VimspectorEval command used `-bar` but this prevented the use of double quotes. This seems much more useful than a vim comment in this scenario, so remove the `-bar`.

This is _techncially_ breaking change, but I don't think it's likely anyone will be relying on doing `VimspectorEval x | something else`. If they are, sorry.
