[Feature] Unused fields in conditions should be zero

[mdX7]

Is your feature request related to a problem? Please describe.
When first creating a quest state condition (e.g. for phase_area) with flags 2|8 and then changing the exact same condition to objective complete and generate SQL the generated data will contain the 2|8 in ConditionValue2 from the previous condition.

Describe the solution you'd like
Zero all unused fields of the used condition on sql generation

Additional context
Setting initial conditions

Changing condition type

Generating sql results in

DELETE FROM `conditions` WHERE (`SourceTypeOrReferenceId` = 26) AND (`SourceEntry` IN (493));
INSERT INTO `conditions` (`SourceTypeOrReferenceId`, `SourceGroup`, `SourceEntry`, `SourceId`, `ElseGroup`, `ConditionTypeOrReference`, `ConditionTarget`, `ConditionValue1`, `ConditionValue2`, `ConditionValue3`, `NegativeCondition`, `Comment`) VALUES
(26, 5950, 493, 0, 0, 48, 0, 12341234, 10, 0, 0, 'Player has completed objective 12341234 (but hasn\'t rewarded quest yet)');

(Notice the 10 for ConditionValue2)
