Re-add AppModeFull annotation.

The annotation was ...taken by another test, causing
isAppInactive_Charging to start running for instant apps again. Adding
the annotation back so it doesn't run for instant apps.

Bug: 150889948
Test: make cts -j 64 && cts-tradefed run commandAndExit cts --module-parameter INSTANT_APP -m CtsUsageStatsTestCases -t android.app.usage.cts.UsageStatsTest#testIsAppInactive_Charging
