Hotfix: Do not divide by adjustment if it equals 0
Hotfix: Do not divide by adjustment if it equals 0

These changes fix issue https://github.com/salesagility/SuiteCRM/issues/7926

The OAuth clients/tokens page has no widths defined, resulting in the totalWidth being 0, and so does the adjustment. The quickfix is to prevent dividing by the variable in such case, avoiding division by 0. When it does, we just set the final value to 0.
