Never say ‘report is 100% complete…’ on job page

This message is meant to indicate that generating the report is still in
progress. Saying 100% contradicts this because 100% sounds like
‘complete’.

Reason this is happening is because rounding 99.5 to 0 decimal places
gives you 100.

So let’s make sure it never gets above 99.0
