Fix to NullPointerException when activity is relaunched

When ChooseTypeAndAccountActivity is relaunched and resumed
by ActivityManager a call is made to onActivityResult without
first triggering onResume. This leads to mAccounts object
still being null.

Fixed by properly setting mAccounts object if it is null prior
to use after function onCreate has been called.

FLAG_PRIVILEGED disappears if privileged app is updated and rebooted

Since Kitkat, an app pre-loaded under /system/priv-app/ has
FLAG_PRIVILEGED. However, if the app updated and the device
rebooted, privileged flag is unset from pkgFlags. This patch
fix issue to assign privileged flag when scanning the updated
packages.

Perform NTP lookup at Mobile data connections

If NITZ isn't supported by the current carrier the Android framework
relies instead on a remote NTP server to set the system clock. The
NetworkTimeUpdateService class polls for NTP time during the first 4
minutes after boot, failing to get NTP time within these minutes will
increase the polling interval to 24 hours. Hence, if a data connection
isn't activated directly after boot it can take a long time for the
system clock to be updated. To prevent this situation, NTP lookup is
scheduled as soon as a Mobile data connection has been established.

UI not updated correctly in expanded statusbar

Sometimes when getting status changes in expanded statusbar the
text disappear. Both NetworkController and PhoneStatusBar handles
UI updates and they are not in sync. This fix allows PhoneStatusBar
to update UI when NetworkController is updating the UI.
