Unable to select custom post types from settings panel

[juliobranha]

Description of the bug

When setting the query block to select custom(s) post types, the selector works fine within the editor, but not on the sidebar, where instead of posts of the custom post types, posts of type post display in the search results

Steps To Reproduce

1. Add a query block as the one below and set postTypes to custom(s) post types <!-- wp:wp-curate/query {"postTypes":["my-cpt"]} --><div class="wp-block-wp-curate-query"><!-- wp:post-template --><!-- wp:wp-curate/post --><div class="wp-block-wp-curate-post">My markup</div><!-- /wp:wp-curate/post --><!-- /wp:post-template --></div><!-- /wp:wp-curate/query -->
2. On the query block sidebar go to Select posts and try selecting one
3. Instead of seeing the posts of my-cpt, posts of post type are displayed
