GlotPress project not re-activated after a theme is unsuspended

[dd32]

​As reported in Slack by @kafleg, a theme may be listed as inactive on translate.wordpress.org when the following conditions are met:

1. The theme is suspended (temporarily)
2. The theme is marked as published again
3. The theme receives no further updates

Upon a theme being suspended, we mark it as inactive in GlotPress, but upon the theme moving from suspend to publish, we don't make the same call.

If a new version of the theme is submitted, that marks the theme as active in GlotPress.

Theme Directory: When a theme is published, mark the GlotPress project and wp-themes.com as available.

See #7213.

Sourced the themes that are labeled as unavailable, marked them as available.

This has introduced a bug where wp-themes.com is updated with a stale version of the "live" theme when a user uploads a new theme version.

Theme Directory: Return when published to prevent duplicate imports

wporg_themes_glotpress_mark_as_active_on_publish() was only intended to run when a suspended/delisted theme was reinstated, but it was also running when a new version of a published theme was uploaded. That caused wporg_themes_update_wpthemescom() to run a second time, after it was originally called by the import process. The second time it was called with the _previous_ version of the theme, though, because it ran before the _status value was updated in the database. That caused previews on wp-theme.com to always show the previous version instead of the current one.
