[Bug] Tests failing when directive does not have inputs and outputs

[gund]

In this case angular does not create property ngBaseDef on the directive class and thus consequent property accesses fail here:

ngx-testing/projects/ngx-testing/src/lib/util.ts

Lines 9 to 10 in f45e5b5

	export function getDirectiveIO<T>(dirType: Type<T>): DirectiveIO {
	const { inputs, outputs } = (dirType as any).ngBaseDef;

This access has to be guarded.
