resourceloader: Disable ChronologyProtector on load.php (again)

This was already disabled in 2016 with 98c6743413118f by calling
setRequestInfo() to override the default 'ChronologyProtection' value
from Setup.php.

This stopped working since 4ccb228bde9294d96d which made
getDBLoadBalancerFactory (in ServiceWiring) obtains a LoadBalancer
from MWLBFactory::setSchemaAliases, and requestInfo is not
re-evaluated after that.
