fw/uiauto: Add method to baseclass to dismiss android version popup

In Android Q a popup will be displayed warning if the application has
not been designed for the latest version of android. This has currently been
dealt with on a per workload basis however this is a common popup so
add a method to dismiss the popup if present to the base class.
