Fix moment rendering bug (#2199)

While we are rendering Problems table for each cell we use a different
renderer. For `Age` field we didn't pass the data properly and it caused
errors. The problem is we were trying to render the whole moment object
instead of just the datatime.

Part of: https://github.com/grafana/grafana-zabbix/issues/2197

This PR will fix the issue. This happens when user wants to add a new
panel with `Age` field or try to edit a problems panel `Age` field
enabled.
