CPT: always use same PackageManager flags to query installed packages

CPT applies the flags MATCH_DISABLED_UNTIL_USED_COMPONENTS and MATCH_HIDDEN_UNTIL_INSTALLED_COMPONENTS when query installed packages
during initialization. But it doesn't apply the same flags when handling packages change. Without those flags, when carrier app falls into bundled version, CPT may fail to find it and report no carrier apps nor carrier privileges.

To fix it, the same flags are always applied, both during initialization
and after any package change events.
