Make Web IDE commit check more reliable

See merge request gitlab-org/gitlab!41245

- When commiting via the Web IDE, check that the commit is complete
  by waiting for the IDE to return to Edit mode and for the commit SHA
  to change. This should be more reliable than checking for text that
  only appears for a moment.

This prepares the service and worker classes for post-processing of
group wikis, though we're not actually implementing any custom behaviour
for group wikis yet.

Wiki models:

- Move `HasWiki#after_wiki_activity` into `Wiki#after_wiki_activity`,
  and add `Wiki#after_post_receive` for container-specific background
  processing.

PostReceive worker:

- Move project-specific code into `ProjectWiki#after_post_receive`.
- Tweak check for project snippets with a missing project, to avoid
  catching group wikis.
- Remove redundant specs for ES indexing, which is already covered
  elsewhere.

Git::WikiPushService (also in EE):

- Change the service to take the wiki as its main argument.
- For group wikis, don't attempt to create events, index Elasticsearch,
  or run Geo services.

Instead of writing a file, we can just stub the existing flags. Also use
`fast_spec_helper` for a faster run with a cold start.
