userman 15.0.65 creates bad crontab entry

This update adds the following crontab entry:

*/15 * * * * [ -e /usr/sbin/fwconsole ] && sleep $((RANDOM%30)) && /usr/sbin/fwconsole userman --syncall -q

resulting in repeated emails:

Subject: Cron <asterisk@FreePBX> [ -e /usr/sbin/fwconsole ] && sleep $((RANDOM
X-Cron-Env: <SHELL=/bin/sh>
X-Cron-Env: <HOME=/home/asterisk>
X-Cron-Env: <PATH=/usr/bin:/bin>
X-Cron-Env: <LOGNAME=asterisk>

/bin/sh: 1: Syntax error: Missing '))'

The added crontab entry needs to be:

*/15 * * * * [ -e /usr/sbin/fwconsole ] && sleep $((RANDOM\%30)) && /usr/sbin/fwconsole userman --syncall -q
