[emotiva] volume db channel for main zone does not work

[espenaf]

Expected Behavior

It should be possible to adjust the main zone volume via a Number:Dimensionless typed channel.

Current Behavior

No change is applied when trying to adjust the main-zone#volume_db channel.

Possible Solution

The channel should be named main-zone#volume-db instead of main-zone#volume_db.

Steps to Reproduce (for Bugs)

1. Assign channel main-zone#volume_db to item and Setpoint element
2. Try to adjust volume

Context

Initially many of the channels had underscore in them, and in the process of renaming them, this one was left out. The main-zone#volume channel still works, so the impact is somewhat limited.
