For the submission and comments, I mainly decided to use a `has_one` association. Based on the database schema, multiple request for comments could be allowed (i.e., for each file or submission), but this won't happen practically (since we always create new submissions and files). Hence, the `has_one` association is representing our relationship better.
* Ensure only one `pp_work_alone` event is stored.
* Disable Turbolinks for Programming Groups Work Alone, so that the implement page is requested normally. Otherwise, Turbolinks would load the page first, just to notice that it needs to reload the page afterwards to include Highlight.js for the tips.
We might receive a `RecordInvalid` error, if one part (such as the external user) is already assigned (not unique). Hence, we just retry.
Fixes CODEOCEAN-TZ
Further, we remove the "check invitation" button and extract some methods to our new ProgrammingGroups object in JavaScript.

The new ACE editor introduces full support for emojis (and, thereby, UTF-16 characters with high- and low-surrogates). Hence, we can remove our custom fix.
Further, this update will allow emojis to be used in pair programming sessions.
This change allows us to use the session ID immediately for the connection_change and connection_status methods. Hence, we can identify different browser sessions of the same user.
Previously, we were at an ACE editor published between 1.1.8 and 1.1.9. This caused multiple issues and was especially a problem for the upcoming pair programming feature. Further, updating ace is a long-time priority, see https://github.com/openHPI/codeocean/issues/250.
Now, we are not yet updating to the latest version, but rather to the next minor version. This already contains breaking changes, and we are currently interested to keep the number of changes as low as possible. Further updating ACE might be still a future task.
The new ACE version 1.2.0 is taken from this tag: https://github.com/ajaxorg/ace-builds/releases/tag/v1.2.0.
We are using the src build (not minified, not in the noconflict version), since the same was used before as well.
Further, we need to change our migration for storing editor events. Since the table is not yet used (in production), we also update the enum.
