[BUG] `no-useless-await` is applied to locator methods regardless of receiver object

[ppath]

For the locator methods, the check is only against the method name and not the receiver object type. Therefore, in the following example the await before a.locator(); is marked as useless:

class A {
  locator(): Promise<void>;
}
async function () {
  const a = new A;
  await a.locator();
}

It seems the relevant logic is here, and I wonder if there could be an additional check on the receiver object for locator methods, like the one for page methods.

This is intentional. We prefer false positives that can be ignored than false negatives that go uncaught.
