test(findMany): add failing test for querying by null

[kettanaito]

• Fixes Querying for null values #186

[kettanaito]

Querying nullable fields by null is a legal operation.

Insights

I suspect that the type produced by Value is not correct:

data/src/glossary.ts

Lines 211 to 212 in d32f154

	Target[Key] extends NullableProperty<any>
	? ReturnType<Target[Key]['getValue']>

First of all, it misses the | null union type. But even when added, it still remains just a plain model value type without the null union. I have no idea why this happens, neither I have the tools to debug this with the current types complexity of Data.

Eventually, a null check must be introduced to the queryTypes.ts to produce a proper query type:

data/src/query/queryTypes.ts

Lines 88 to 89 in d32f154

	export type GetQueryFor<ValueType extends any> = ValueType extends string
	? StringQuery

Update

1.0 most likely fixes this. The task is now to see if this test exists in the new test suites and if it doesn't, add it.
