Fix PHP 8.1 "strlen(null)" exceptions which block rendering the DarkConsole

Browse source 
Summary:
Since PHP 8.1 the function call `strlen(null)` is deprecated.

Since Phabricator/Phorge elevates deprecation warnings to exceptions, the
specific fix implies dealing with null, and dealing with real strings.

In the specific case, a simple cast was made to deal with real strings.

Closes T15315

Test Plan: Visit the Home Page with DarkConsole enabled in your configuration: no crashes
