Common - Fix calling getVar on null object in canInteractWith

[PabstMirror]

Prime a grenade in adv_tossing and it spams rpt with

getVariable called on null object
 ➥ Context: 	[] L49 (z\ace\addons\advanced_throwing\functions\fnc_prepare.sqf)
	[] L18 (z\ace\addons\advanced_throwing\functions\fnc_drawThrowable.sqf)
	[] L18 (z\ace\addons\advanced_throwing\functions\fnc_drawThrowable.sqf)
	[] L32 (z\ace\addons\advanced_throwing\functions\fnc_canPrepare.sqf)
	[] L33 (z\ace\addons\advanced_throwing\functions\fnc_canPrepare.sqf)
	[] L24 (z\ace\addons\common\functions\fnc_canInteractWith.sqf)

there is a call with null target

{[_unit, objNull, [...]] call EFUNC(common,canInteractWith)}

and in 2.06 calling getVar on a null throws rpt warning (but no popup even with showscript debug)

edit: this is a profiling branch thing

• Added: Debug log message with context for when a script tries to getVariable on objNull/grpNull

and in 2.06 calling getVar on a null throws rpt warning

Only with -debug mode enabled, and it got disabled when default value is provided (which you have) or unscheduled (which you have too)

TLDR this RPT warning won't happen for you there.

So both changes harm performance (eeeever so slightly) and are not needed.
