[BUG] Null config causes fatal error on config commands

[PabstMirror]

Describe the bug Null config causes fatal error on config commands (isClass, isText, getNumber ...)

To Reproduce Steps to reproduce the behavior: .\sqfvm.exe --automated --sqf "isClass configNull;"

Executing...
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
[ERR] [L1|C0|__commandline]     Provided value is null.
[FAT] [L1|C0|__commandline]     Stacktrace:<  1 of 1> [L1|C0|__commandline]     [missionNamespace] [SCOPENAME-EMPTY]
isClass configNull;
^^^^^^^

Expected behavior

• isClass configNull - Expected: false, gives fatal error
• getNumber configNull - Expected: 0, gives fatal error
• getText (configFile >> "doesNotExist") - Expected "", gives fatal error
• isNull configNull - Expected: true, this does work correctly!

[X39]

Is the expected behavior cross-checked with arma?
