[pve-devel] [PATCH manager] replication: fix uninitalized warning

[Fabian Grünbichler]

if a job has no schedule and is executed via "Schedule now" but fails, the
following will be printed to journal/syslog:

Mar 21 13:05:01 host02 pvescheduler[203343]: send/receive failed, cleaning up snapshot(s)..
Mar 21 13:05:01 host02 pvescheduler[203343]: 100-0: got unexpected replication job error - command 'set -o pipefail && pvesm export local-zfs:vm-100-disk-0 zfs - -with-snapshots 1 -snapshot __replicate_100-0_1679400300__ | /usr/bin/ssh -e none -o 'BatchMode=yes' -o 'HostKeyAlias=host03' root at 10.0.74.3 -- pvesm import local-zfs:vm-100-disk-0 zfs - -with-snapshots 1 -snapshot __replicate_100-0_1679400300__ -allow-rename 0' failed: exit code 255
Mar 21 13:05:01 host02 pvescheduler[203343]: Use of uninitialized value in concatenation (.) or string at /usr/share/perl5/PVE/API2/Replication.pm line 107.

defaulting to the fallback schedule '*/15' makes the spurious warning go away.
