users_refresh_time=0s does not work as documented

The documentation for users_refresh_time states:

A value of 0 allows infinite refreshes and a negative value disables the refreshing entirely.

Configuring MaxScale with users_refresh_time=0s does not do this and produces the following message:

2024-04-17 13:29:14   warning: (7) [MariaDBProtocol] User accounts have been recently updated, cannot update again for 'test5'@'::ffff:192.168.122.1'.

The expected behavior is that this message is never logged and all newly created users are always available.
