fix(notifications channel/destination update entity): Updated provider to work with new client version

[amaor-newrelic]

Description

Please include a summary of the change and which issue is fixed (if relevant).

Currently there's no way to update the boolean field "active" to be false, as the "omitempty" tag(?) parses false as empty. The change has been done in the client and it is a breaking change, so this PR was created to work with the new version

This will be nil if there is no active property, right?

Do you need to upgrade the go-client version here?

Also, looks like tests are failing :)
