calamaris: Bug fix for proxy reports staying empty after Core 136 upgrade

After upgrading to Core 136, 'calamaris' "Proxy reports" stayed empty.
GUI always show "No reports available".

Tested manually on console stops and throws an error:

...
root@ipfire: ~ # /usr/bin/perl /var/ipfire/proxy/calamaris/bin/mkreport
1 0 2019 8 10 2019 -d 10 -P 30 -t 10 -D 2 -u -r -1 -R 100 -s
Can't use 'defined(%hash)' (Maybe you should just omit the defined()?)
at /var/ipfire/proxy/calamaris/bin/calamaris line 2609.
...

Line 2609 was changed and reports are built again.
