AndroidGCS Telemetry: Make the connected signal only occur after all objects

are downloaded

In the case of a flaky connection this will render telemetry mostly masked
from the activities.  However, it ensures that all the information is present
after a connection.

Some compromise is probably needed for using this in the field, such as a
tiered system:
1. Physical channel open (no idea about reception)
2. Link estabilished (at least some reception)
3. Full telemetry established (all objects synced up)
