CBA_fnc_compatibleItems throws undefined variable errors when called with a single parameter

[jaj22]

Mods (complete and add to the following information):

• Arma 3: 2.16 stable
• CBA: 3.17 release, whatever that is

Description:
CBA_fnc_compatibleItems throws an undefined variable error when called with a single parameter in scheduled execution, eg:

0 spawn {
  ["arifle_MX_F"] call CBA_fnc_compatibleItems;
};

Results in:

19:37:53 Error in expression <key = format ["%1#%2", _weapon, ["all", _typefilter] select _typeFilterExists];>
19:37:53   Error position: <_typefilter] select _typeFilterExists];>
19:37:53   Error Undefined variable in expression: _typefilter
19:37:53 File /x/cba/addons/jr/fnc_compatibleItems.sqf..., line 267

The select is invalid in scheduled mode because _typefilter is dereferenced regardless of the value of _typeFilterExists.

This breaks several routines in Antistasi because the function also replaces BIS_fnc_compatibleItems.

_typefilter is by default nil, and previously if-then only evaluated it if _typeFilterExists == true. With select both expressions in array are resolved either way, causing this error.

This should be written better to begin with.
