misc/objectManager: Fix emission of object-removed signal

Browse source 
Emitting this signal is broken right now: We check for a length of 0 on
this._objects[objectPath], but the
`this._objects[objectPath][interfaceName] = null` we do before the
check doesn't actually remove the key, it only sets the value to null,
leaving the key around and thus the amount of entries in the object doesn't
change.

Fix that by using the delete statement instead, "delete" properly removes
the key and thus affects the amount of entries in the object, making our
length === 0 check effective.
