Fix race condition in PackageManager.
When Google Play installs 2 apps concurrently (e.g.
personal and work profile) PackageManager can hit a
race condition when connection to media container has
not yet been established but the MCS_BOUND event is
triggered from MCS_UNBIND.
Detailed step by step scenario:
1. package1 comes in
2. INIT_COPY (initiate bind, add pending install)
3. onServiceConnected triggers (MSC_BOUND)
4. MSC_BOUND, process pending package and schedule MSC_UNBIND
5. MSC_UNBIND is triggered once the package is verified
6. service is diconnected
7. package2 comes in
8. INIT_COPY (initiate bind, add pending install)
9. MSC_UNBIND scheduled at step 4
10. MSC_UNBIND sees that there is a pending package,
schedules MSC_BIND
11. MSC_BIND arrives before service is connected and we fail.
Solution: do not fail if we wait for connection.
