Syntax error in facebook_album.schema.yml

When i was importing config from my colleague I got error:

exception 'Drupal\Core\Config\UnsupportedDataTypeConfigException' with message 'Invalid data type in config facebook_album.schema, found in                           [error]
filemodules/contrib/facebook_album/config/schema/facebook_album.schema.yml : yaml_parse(): scanning error encountered during parsing: mapping values are not allowed
in this context (line 12, column 21)' in /vagrant/mastale/web/core/lib/Drupal/Core/Config/FileStorage.php:117

After little debugging I have noticed that there is syntax error in config/schema/facebook_album.schema.yml. Same error is in stable and dev version of this module (Drupal 8 version).

I have created patch that should fix this syntax error.
