Show better human readable tooltip for app token

[Kristina Hoeppner]

When you set up a mobile app token for Mahara at /module/mobileapi/apps.php (User menu -> Settings -> Apps).

The tooltip - and thus I believe also the screenreader text - only shows some cryptic numbers when hovering over the "Delete" button instead of mentioning the app and the device (see screenshot).
