SPELL_ATTR3_ONLY_TARGET_PLAYERS should get ignored at _ENTRY target types

[Ovahlord]

Description:
I just discovered a issue with SPELL_ATTR3_ONLY_TARGET_PLAYERS.
Spell ID - 74634 Ground Siege for example is suposed to deal damage to players only. This is the case for EFFECT_1 and EFFECT_2. But EFFECT_0 is a dummy effect that is suposed to hit a nearby entry. However. The target for that is an npc and the attribute blocks the selection for the npc. So as conclusion: the attribute should not get taken into account for targets that use _ENTRY target types.

Current behaviour:

SPELL_ATTR3_ONLY_TARGET_PLAYERS blocks xxx_ENTRY targeting.

Expected behaviour:

SPELL_ATTR3_ONLY_TARGET_PLAYERS should not affect target types that involve creature entries.

Steps to reproduce the problem:

1. use this condition: https://paste2.org/BFteI9Hx
2. spawn the target npc by using .npc add temp noloot 40030
3. cast the spell by using .cast 74634 and see how the spell fails even if the target is right in front of you
