Do not call into ActivityManager when holding mSpManager lock

Otherwise deadlock will arise since keyguard related execution flow
calls into LockSettingsService.havePassword() when holding ActivityManager
lock.

Bug: 62533880
Test: 1. Set device with Pattern/PIN/Password
      2. From Quick Settings > Select Add user
      3. From Secondary user welcome screen Click "Cancel" and then choose "Keep user"
      4. Swipe to go to Security lock screen > Tap on Emergency link > Select Emergency Information > Tap on Edit icon
      5. Now unlock the device using PIN/Password/Pattern
      6. No deadlock should be observed
