A backup job in pool mode keeps referencing its pool after the pool got
deleted. Resolving the guests of such a job dies with "pool '<name>'
does not exist", and since get_included_vmids() did not catch this, the
whole /cluster/backup-info/not-backed-up call failed. The GUI then hides
the "Show guests without backup job" button, so users lose exactly the
overview that would tell them some guests are no longer backed up.
Catch the error per job, warn about it and continue with the remaining
jobs. The broken job does not back up anything, so its guests correctly
show up as not covered by any backup job.
Add a test for get_included_vmids() covering this case.

render_mem_usage_percent() treated any value above 1 as a byte count
and recalculated the percentage from 'mem' and 'maxmem'. But the memory
usage ratio of a guest can legitimately exceed 1, for example when the
reported usage is the host-side memory of the QEMU process, which
includes its own overhead. In the reported case, 'mem' was 2222472192
with a 'maxmem' of 2147483648, so the ratio of about 1.035 got taken as
bytes and the search and resource grids showed 0.0 % instead of 103.5 %.
All users of the renderer now pass the usage as a ratio, so drop the
bytes fallback and always render the value as percentage.
