[AMF] Fix the crash since validityTime->30s(#3210)

Browse Source 
We're experiencing an issue after changing SearchResult.validityTime
from 3600 seconds to 30 seconds.

When AMF finds a PCF through Discovery, it can be deleted
after 30 seconds by ValidityTime.

We have changed our implementation to not send the PCF-ID in this case.

What we need to do is proactively add a part that will re-discover
the PCF when a situation arises where we really need the PCF-ID.
