Incompatibility with jsonapi

Hello,

While testing to reproduce a bug in the JSON API issue queue, I found an error provoked by dynamic entity reference #2841850-4: Internal Server Error with Grouped Filter Conditions while I was not requesting a dynamic entity reference field.

Steps to reproduce:

1. On a Drupal site with the JSON API and the dynamic entity reference modules enabled
2. maybe optional: Set a content type with a dynamic entity reference field
3. Request a JSON API endpoint on a different content type with a filter on a referenced entity value. See https://www.drupal.org/node/2803141, "Filtering examples", case 2 "Nested Filters: Get nodes created by user admin", the URL would look like: jsonapi/node/page?filter[name-filter][condition][path]=uid.name&filter[name-filter][condition][value]=admin

There is a fatal error:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'node_field_data.uid_int' in 'on clause': SELECT base_table.vid AS vid, base_table.nid AS nid
FROM
{node} base_table
INNER JOIN {node_field_data} node_field_data ON node_field_data.nid = base_table.nid
LEFT OUTER JOIN {users} users ON users.uid = node_field_data.uid_int
INNER JOIN {users_field_data} users_field_data ON users_field_data.uid = users.uid
WHERE (users_field_data.name LIKE :db_condition_placeholder_0 ESCAPE '\\') AND (node_field_data.type = :db_condition_placeholder_1)
GROUP BY base_table.vid, base_table.nid
LIMIT 51 OFFSET 0; Array
(
[:db_condition_placeholder_0] => admin
[:db_condition_placeholder_1] => article
)

Due to dynamic_entity_reference/src/Query/Tables.php.

I do not understand why this class is used as it is not a dynamic entity reference field that is required.

Thanks for any help, and I will be glad to provide a patch.
