Deleting google plus config on install causes problems with site install and config split

Hey all,

After reviewing this, I think the problem lies in the install hook -- not the update hook.

/**
 * Remove google plus configuration.
 */
function social_media_update_8001() {
  \Drupal::configFactory()->getEditable('social_media.settings')->clear('google_plus')->save();
}

/**
 * Implements hook_install().
 */
function social_media_install() {
  social_media_update_8001();  <-- Let's just delete this line! 
}

We probably don't have to call the update hook from within the install hook because the module doesn't ship with default configuration for google plus anymore. In other words, new users installing the module won't have any google_plus config for us to delete :-). This should alleviate the BLT problem without needing to add any additional logic into the mix.

If someone can re-roll this change against 2.0.x, I'd gladly review and merge it in.

Cheers!

I will work on this patch reroll and provide the update.

Addressed #3 and rerolled the patch for 2.0.x. Please review
