ConnectionPool: fix gun open errors being returned without an error tuple

When gun shuts down due to the host being unreachable, the worker
process shuts down with the same shutdown reason since they are linked.
Gun doesn't have error tuples in it's shutdown reason though, so we need
to handle it in get_conn.

Closes #2008
