PHP error during site install due to key not existing

Hi everyone,

This causes the install process to fail because the "__construct" method in "FlickrIntegrationSuiteApiProvider.php" attempts to load the API key from the "keyRepository" service, which returns null at that point.

See the error below

[error]  Error: Call to a member function getKeyValue() on null in Drupal\flickr_integration_suite\FlickrIntegrationSuiteApiProvider->__construct() (line 100 of /home/travis/build/nyunursing/meyers/docroot/modules/contrib/flickr_integration_suite/src/FlickrIntegrationSuiteApiProvider.php) #0 [internal function]: Drupal\flickr_integration_suite\FlickrIntegrationSuiteApiProvider->__construct(Object(Drupal\Core\Config\ConfigFactory), Object(Drupal\key\KeyRepository), Object(Drupal\Core\Http\ClientFactory), Object(Drupal\Core\Messenger\Messenger), Object(Drupal\Core\Cache\MemoryBackend))

Here's a patch that checks whether the key config exists before calling the "getKey" method:
