first is not friendly with isPresent

[rinnnn]

ElementArrayFinder.first() (and probably last too) is not currently friendly with the ElementFinder.isPresent. I.e. assume the following test:

it('First should be friendly with isPresent', function () {
    expect(element.all(by.css('nonexistingselector')).first().isPresent()).toBe(false);
});

That is quite natural assumption but the test is not passing. It fails currently with the error:

Failed: Index out of bound. Trying to access element at index: 0, but there are only 0 elements that match locator By.cssSelector("nonexistingselector")

Can this be improoved somehow?

PS.
Actually I faced it in a more complex case where I was trying to do something like this:

function byExactText(text) {
    // Cannot use by.cssContainingText here because
    // I need item with name "Element1" whereas
    // there also is another item with name "Element1 Extended".
    return element.all(by.css('.item')).filter(function(item) {
        return item.element(by.css('.name')).getText().then(function(text) {
            return text === name;
        });
    }).first();
}
expect(byExactText('Element1').isPresent()).toBe('false');
expect(byExactText('AbsentElmnt').isPresent()).toBe('false');

And here I cannot easily replace to something like:

byExactText('AbsentElmnt').then(function(items){
    return items.length > 0 ? items[0] : undefined; // well, what to replace the indefined with?
}).isPresent();

Because the yet-unresolved-promise returned from "then" is not an instance of ElementFinder and has no appropriate methods...

PPS. This issue has something common with #2314

So the issue is that the code fails on the first() call before passing on to isPresent(). I think it's a reasonable feature request to find a way to get isPresent to work in this case.

I'm actually running into this exact same issue:

function filterMdCards(attText){
        element.all(by.css('elementAtt')).filter(function(elm,` index) {
            return elm.getText().then(function(txt) {
                return txt === attText;
            });
        }).first().click();

The error I see is the same index out of bound error.
