## Are there points in the code the reviewer needs to double check?

In order to get multiple alerts to appear manually while testing, I simply added the following block to [app/views/shared/_no_password.html.haml](app/views/shared/_no_password.html.haml):

```

.no-password-message.alert.alert-warning.hidden-xs
  You won't be able to pull or push project code via #{gitlab_config.protocol.upcase} until you #{link_to 'set a password', edit_profile_password_path} on your account

  .pull-right
    = link_to "Don't show again", profile_path(user: {hide_no_password: true}), method: :put
    |
    = link_to 'Remind later', '#', class: 'hide-no-password-message'

.no-password-message.alert.alert-warning.hidden-xs
  You won't be able to pull or push project code via #{gitlab_config.protocol.upcase} until you #{link_to 'set a password', edit_profile_password_path} on your account

  .pull-right
    = link_to "Don't show again", profile_path(user: {hide_no_password: true}), method: :put
    |
    = link_to 'Remind later', '#', class: 'hide-no-password-message'

.no-password-message.alert.alert-warning.hidden-xs
  You won't be able to pull or push project code via #{gitlab_config.protocol.upcase} until you #{link_to 'set a password', edit_profile_password_path} on your account

  .pull-right
    = link_to "Don't show again", profile_path(user: {hide_no_password: true}), method: :put
    |
    = link_to 'Remind later', '#', class: 'hide-no-password-message'
```


## Why was this MR needed?

More alert-warning stripes are coming via the CI usage limits implementation in EE (https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/965), and these layout margins and colors were becoming messy.

Make autocomplete request performant

## What does this MR do?

Restricts the `autocomplete_sources`action to returning the `json`of one specific `at` type at a time.

Makes sure all commands start by immediately showing the `loading` dropdown.

If the `loading` dropdown is active, we will request and load in the data for that specific `at` type. We manually trigger the filter again. This time, if `loading` dropdown is not active, initiate default filter behaviour and use the correct data template.

Also fixes an issue where `setup` was called multiple times by only setting up and destroying atwho on a focused/blured input.

## Are there points in the code the reviewer needs to double check?

## Why was this MR needed?

`autocomplete_sources` was requested on page load and is large.

## Screenshots (if relevant)

3 requests for 3 different first-time references.
