NPE from `bb quickblog watch` on new blog

[jmglov]

Steps to reproduce:

1. Create a new directory such as qb-test
2. Add a bb.edn with the following contents:

   {:deps {io.github.borkdude/quickblog
           #_"You use the newest SHA here:"
           {:git/sha "8f5898ee911101a96295f59bb5ffc7517757bc8f"}}
    :tasks
    {:requires ([quickblog.cli :as cli])
     :init (def opts {:blog-title "REPL adventures"
                      :blog-description "A blog about blogging quickly"})
     quickblog {:doc "Start blogging quickly! Run `bb quickblog help` for details."
                :task (cli/dispatch opts)}}}

3. Run bb quickblog new --file test1.md --title "This is a test for echo..."
4. Run bb quickblog watch

You'll see an exception like the following:
