commands: fix panic in template execution
Fix a panic in the template execution when the template evalutes to nil.
Check for length of returned arguments after the template code is
expanded.
To reproduce, run :{{exec "cat > /dev/null" .MessageId}}
Fixes: 42cd4157 ("commands: execute commands with templates")
