A style issue

[asmsuechan]

context

The new note button has a weird style. The protrusion should be removed.

The file is https://github.com/BoostIO/Boostnote/blob/master/browser/main/NewNoteButton/NewNoteButton.styl

how to reproduce

1. create a new empty folder
2. access it
3. look at the button
