[qase-cypress] No check for null in qase method

[DanilTaGiL]

At this moment:
https://github.com/qase-tms/qase-javascript/blob/7a279b5e3bcffeafe4cd9a0de84161dffa1f5752/qase-cypress/src/mocha.ts#L3-L5 Should be smth like this:

    qase: <T>(caseId: number | string | number[] | string[], test: T): T => {
        if (!test) {
            return test;
        }
        const testNew = test as unknown as Record<string,string>;
        let caseIds: number[] | string[];

I try this fix locally, it solve the problem.

I found this problem when use cypress-grep together with qase-cypress. There's a feature that we could omit tests after grep. But this is return null tests. And as there no check for null, in this case test run will broke up.
