[make:entity] don't set array field default value for nullable column

Setting a default value will lead to a wrong (not nullable) return value of the getter method.

Also setting a default value on a nullable field somehow cancels out the intention of nullable (except for setting it explicitly).

I'm not sure if this should be treated as a bc break. but since no existing properties are overwritten i think it should be fine.
