* Ensure $template is object before accessing properties
This is necessary because the gutenberg helper functions sometimes turn it into a WP_Block_Template object, and other times it's an array. Because of this it's safer to normalise them both as objects.
* Add Gutenberg utils for processing templates based on a post from the db
When a template is saved it gets saved to the database, we need to handle processing these WooCommerce templates that have been saved in the db and we need to use the gutenberg utils that are private, this is why they've been copied over.
* Force theme to always be WooCommerce
This is because the templates we're dealing with here should always belong to WooCommerce, not the currently selected theme
* Add maybe_return_blocks_template and get_single_block_template funcs
These are needed to get the template from either the DB or the filesystem when saving/retrieving the template.
* Set theme to always be woocommerce when making templates from files
This will ensure the correct slug is used in the gutenberg editor.
* Check if template has been customised and saved in the database first
* Prevent filesystem templates being used if a custom database one exists
* Fix syntax error from rebase
* Remove unnecessary code from BlockTemplateUtils
* Ensure template item is an object containing correct properties
* Prevent warnings from appearing
* Ensure title is added to the template when saving
* Filter templates that don't match the queried slug.
* Remove unused code
* Check if a saved version of the template exists when trying to render
* Rename default_block_template_is_available to block_template_is_available
* Re-hook pre_get_block_template before returning from maybe_return_blocks_template
* Make comment easier to read
* Look for template in woocommerce theme or real theme taxonomy
* Remove duplicated title assignment
* Prevent template being added twice when loading from the db
* Filter templates before returning if slugs are supplied
* Simplify `get_block_templates` function into two functions
* Add function to stop theme templates that are added after db ones showing
* Fix typographical errors
* Copy logic from Gutenberg to ensure the correct templates are being included in the get_block_templates query
* Utility function to convert template slugs to template titles
* i18n strings for template names
* Add render logic to BlockTemplatesController
* Comment out action to test e2e tests
* Add add_action back into initialise render method
* Check function exists before using it
* Change hook from wp to template_redirect
* Update src/BlockTemplatesController.php
