Fixed profiler formatting (#28)

Some minor adjustments were made to improve readability and accuracy of
output. Padding was added to further standardize the spacing of output
values, some conditionals were adjusted, and 'Exit Code' output was
changed from 'Info' to 'Debug' level. Extraneous test assertions were
removed accordingly.
