fix(utilities): race condition issue for closed paginated message (#484)

* fix(utilities): race condition issue for closed paginated message

This commit fixes a bug where the button components won't get removed
due to a race condition error:
`DiscordAPIError: Interaction has already been acknowledged.`.
This occurs when trying to interact with the message when it is about to
close the paginated message.
