Do not create notes with --resource without some --content

[vitaly-zdanevich]

geeknote create --title 'My test title' --resource ~/Desktop/test.jpg
After that I see Vim, I save empty content with ZZ, after that I see usual Note successfully created, but this is not true. My current workaround is to use --content ''.
