Pawel Kozlowski 1fc5442947 perf(core): avoid changes Observable creation on QueryList (#53498)
The changes Observable (impl: EventEmitter) on the QueryList is initalized
lazy - it is created only if someone calls a geter to get a hand on its
instance. But the destroy method was calling this getter thus creating
a new Observable even if no one subscribed to it.

This commit changes the destroy logic to skip creation of an EventEmitter
if it wasn't initialized.
