HittingEscapeOnCloseConfirmationDialogTest: Match dialog by title

This would match the "Close" dialog, by looking for any JDialog on
screen. However, in some cases, there could be a second dialog (I have
seen a "Install this package to use your xxx board" popup because I
happened to have an Arduino Zero connected, presumably an "Updates are
available" popup could cause this as well).

By matching not just the type of the dialog, but also the title, only
one dialog is matched and the testcase runs more reliably.
