Only add presence watching when all OCCs are bound

The OCC present count returns the number of OCCs in the system. Before
we have bound the second OCC, this will be greater than the number of
OCCs the Manager has counted as Active, resulting in a mismatch, causing
an error.

Resolves openbmc/openbmc#2733
