Imports are performed partly without ois_fixes when starting from an empty database

Using v1.5 and starting the import from a completely empty database the first 487 post codes (from 1050 to 1974) are processed without the ois_fixes table being populated.

This results in reversion of previously corrected names resetting OSM fixed names to the names specified by DAR. This happened during the initial production run after server migration done by mikini on 2023-09-30. The post codes and street names which were affected before intervention were:

1820 Frederiksberg C, "Frederiksberg Allé" -> "Frederiksberg Alle": 141937671 (achavi)
1854 Frederiksberg C, "Doktor Priemes Vej" -> "Dr. Priemes Vej": 141937848 (achavi)
1955 Frederiksberg C, "Doktor Abildgaards Alle" -> "Dr. Abildgaards Alle": 141939123 (achavi)
1961 Frederiksberg C, "J.M. Thieles Vej" -> "J.M.Thieles Vej", 141939287 (achavi)

The cause is the condition of index.php:30 which makes the update of ois_fixes & post codes happen only when the post code being processed is divisible by 1000. As the lowest post code in use by DAR is 1089 this does not happen before 2000 is hit, disregarding ois_fixes (missing post codes are handled specifically) on all post codes below on that initial run (or whenever the db is dropped/ois_fixes cleared).
