Fix Doom upgrade command

[reinaldoossuna]

fix #960

[xeruf]

[reinaldoossuna]

line 82

if let Some(doom) = &self.doom {
    Emacs::update_doom(doom, ctx)
} else {
    let init_file = require_option(self.directory.as_ref(), String::from("Emacs directory does not exist"))?
	....

LET SOME DOOM
SELF DOOM
