Add possibility to check condition of widget and widget elements if widget not present on screen.

[HlebHalkouski]

Description

In the current implementation when we invoke any method of widget or widget elements, if widget not present on screen, throws NoSuchElementsException.

Environment

• java client build version or git revision if you use some shapshot: 5.0.0-BETA7

Details

Example: we have class:

public class MobileBlock extends Widget {
    
@AndroidFindBy(id = "main")
public MobileElement element;

    protected MobileBlock(WebElement element) {
        super(element);
    }

    public boolean isDisplayed() {
        return getWrappedElement().isDisplayed();
    }
}

If we try invoke method isDisplayed in MobileBlock class when widget is not present we have NoSuchElementException.
Or try to check visibility of widget element we also have NoSuchElementException.

The similar issue has already been closed as By Design in original Selenium project. Why should Appium change this behaviour?
