[sumo][PATCH 4/8] toaster/widgets.py: avoid divide by zero issues

There can be cases where the variables being used
to divide in these expressions can be zero. e.g.
a setup consisting of only local repos will have
repos_to_clone=0 and will generate a divide by
zero scenario.
Fix this by checking the divisor in such cases.
