Traverse full domain list when checking for excluded domains

[martosaur]

As per documentation

:excluded_domains - Any messages with a domain in the configured list will not be sent

However, when checking log message domains excluded_domain?/2 function only checks the head element.

This makes it impossible to exclude messages logged with default Elixir logger interface like Logger.error("Message", domain: [:custom_domain]) as their domain is always prepended with :elixir domain
