WHC da04913071 android: read the activity's own arguments, since Qt does not deliver them
`am start -n <pkg>/org.qtproject.qt.android.bindings.QtActivity --esa
applicationArguments "--workspace,/sdcard/x"` left the window on its default
workspace on the NX789J (the plain-string extra too), so the extra is read
from the intent directly. That is what makes `cst-agent-app --uitest
--workspace DIR` reachable on a device with no keyboard -- and adb cannot
inject touch into this window either (tap, touchscreen tap, mouse tap and
motionevent all do nothing; key events do work), so it is the only way in.

Everything degrades to "no arguments": an invalid object, a missing method or
a context that is not an activity all come back empty.
