Add elementArrayFinder.some

[mohsen1]

Following my question here at StackOverflow I think elementArrayFinder.som can be handy for solving my issue there.

elementArrayFinder.some = function(fn) {
      return using().findElements(locator).then(function(arr) {
        return arr.some(function(webElem) {
          fn(webElem);
        });
      });
    };

With that, I can write:

      var isShown = helpers.getRoleRows().some(function(row){
        return row.getText().indexOf(ROLE_NAME) > -1
      });
      expect(isShown).toBe(true);

Should I work on a PR for this?
