AOSP/Calendar - Fix closing of system dialogs broadcast without permission.

Deleted closeNotificationShade method thus not invoking ACTION_CLOSE_SYSTEM_DIALOGS intent.

Test: manual - build tests, unit tests, and
CTS tests were conducted using the following
commands:
$ make Calendar
$ make CalendarTests -j
$ adb install -r  -t -d out/target/product/bonito/product/app/Calendar/Calendar.apk
    Success
$ adb install -r -t -d out/target/product/bonito/testcases/CalendarTests/arm64/CalendarTests.apk
    Success

$ adb shell am instrument -w com.android.calendar.tests

General CTS Tests:
$ tools/cts-tradefed
cts-tf > run cts -m CtsProviderTestCases

The following CTS test results are same as before the change:
