Transform Update User call to async/await

[igeligel]

Issue Summary:

In the auth.module.js here you have got some code like:

[UPDATE_USER](context, payload) {
  const { email, username, password, image, bio } = payload;
  const user = {
    email,
    username,
    bio,
    image
  };
  if (password) {
    user.password = password;
  }

  return ApiService.put("user", user).then(({ data }) => {
    context.commit(SET_AUTH, data.user);
    return data;
  });
}

Those promise calls could be simplified with async and await calls.

Acceptance Criteria:

• A test is introduced, this is perfect work for TDD
• There is no .then(... or .catch(... block or any promise like structure

The main issue can be found here #5

I'll have a go at this one as well
