[pmg-devel] [PATCH log-tracker] fix #3758: fix `to` filter with empty NoqueueEntry `to` field

[Mira Limbeck <m.limbeck@proxmox.com>]

We only compared the filter `to` with the Noqueue `to` when both were
not empty, and in turn set the nq.dstatus to DStatus::Invalid when they
didn't match.
But in the case of an empty Noqueue `to`, we have to skip it as well if
the filter `to` is not empty.
