invoke/invoke.card/invoked got passed on 10.2.x.

However, there're some observations needed to mention:
In general:
1.bbm: uuid needs update to make it work
2.pim.calendar: many failures(it took very long time to finish; device might blink if exit the app during the execution)

On 10.1.x:
1.invoke: 8/10 failed and then the test app couldn't be minimized or closed
2.invoke.card: 7/11 failed
3.pim.contact: 5/53 failed

On 10.2.x:
1.crossOrigin: 2 failed
2.ui.cover: 1 failed
3.crossOrigin: 2/49 failed
4.pim.contact: 3/53 failed

This can be merged. invoked got passed. The other issues are unrelated.
