Auto merge of #27634 - sudarshan-reddy:preferences-actor-returns-real-vals, r=jdm

preferences actor now returns real values.

The preferences actor was previously returning mock values. This changes
picks up the pref_values from the pref_map which is global preferences
state and returns values from there.
