Subject: [PATCH] Remove "quick listener check" and don't mute connection

Commit removes "quick listener check" which mutes connection and returns error
when listener isn't available at the time of inicialization.
It seems as this there is no need to scrap connection, because when remote
endpoint comes around later, metrics will be received by that endpoint just
fine.

Fixes #6
