Block Hooks: Don't erase post content if it isn't changed by client.

The `inject_ignored_hooked_blocks_metadata_attributes` filter that is attached to both the `rest_pre_insert_wp_template` and `rest_pre_insert_wp_template_part` hooks receives a `stdClass` object from the Templates REST API controller that contains all fields that the client would like to modify when making a `POST` request (plus the `id` to identify the relevant template or template part, respectively).

There are cases when the `post_content` field is not set, e.g. when the client would like to rename an existing template (in which case it would only set the `title` field).

Prior to this changeset, the filter would erroneously apply the Block Hooks algorithm to the non-existent `post_content` field regardless, which would result in it being set to the empty string `''`. As a consequence, renaming a template would have the unwanted side effect of wiping its contents.

This changeset fixes the issue by returning early from the filter if the `post_content` field is not set.

Props alshakero, bernhard-reiter.
