Default Variables in Inputs aren't generated.

[Teddy-Schmitz]

Expected Behaviour

Default variables are generated and used when declaring an input.

Actual Behavior

Default variables aren't generated and are ignored.

Minimal graphql.schema and models to reproduce

schema {
    query: Query
}

type Query {
    Test(input: DateFilter): Boolean
}

enum DATE_FILTER_OP {
    EQ
    NEQ
    GT
    GTE
    LT
    LTE
}

input DateFilter {
    value: String!
    timezone: String = "UTC"
    op: DATE_FILTER_OP!
}

snippet of model generated

type DateFilter struct {
	Value    string
	Timezone *string
	Op       DATE_FILTER_OP
}

Experiencing this issue on a build where expected values are resulting in de-reference errors, @vektah should this be working?
