Summary

plugin_order_getDatabaseRelations() still declares a relation between glpi_profiles and glpi_plugin_order_profiles, but that table no longer exists: PluginOrderProfile::install() migrates its data to glpi_profilerights and drops the table.

As a result, deleting any GLPI profile while the order plugin is active triggers a fatal error, since core's cleanRelationData() tries to query a table that doesn't exist:

RuntimeException: MySQL query error: Table 'glpi_plugin_order_profiles'
doesn't exist (1146) in SQL query "SELECT * FROM glpi_plugin_order_profiles
WHERE profiles_id = 'X'"

Fix

Remove the obsolete glpi_profiles entry from plugin_order_getDatabaseRelations().
