musiconhold: Only warn if music class is not found in memory and database.

The log message when a MusicOnHold music class was not found was changed
from debug level to WARNING level in Asterisk 11.19 and 13.5.  For those
using realtime musiconhold, this message is wrong because it warns
before checking the database.

This changeset delays the warning until after the database has been
checked.
