Infinite wait loop in cli when enabling device on a core when owned by another

In a multi-core environment, devices are assigned and owned by a single core.  There is currently an issue when pre-provisioning an OLT on a core and trying to enable it on a second core.  The cli will essentially remain in a "waiting for device to be enabled..." loop.  It seems to never complete the configuration of that OLT.  But the ONUs are configured and set to an enabled/active state.

To reproduce the issue:

1. Start 2 VOLTHA cores (core1 & core2)
2. Start a CLI (cli1) pointing to core1
3. Start a CLI (cli2) pointing to core2
4. Issue a pre-provision on cli1
5. Issue a enable <with pre-provisioned id> on cli2
