fix handling of a default 'template' as a string
Comment fixed: RedrawFrequency is measured in steps.
ProgressHelper shows percentage complete.

In the past the value was rounded, the progressbar ended up being 100% for 0.5%
of the total execution time. That means 18 seconds on a 1 hour process.
merged branch lsmith77/fix_include_default_text (PR #8445)

This pull request has 2 minor changes:
- 199/200 => 99% instead of 100% (there was no test case and I added one, everything else passes) In the past the value was rounded, the progress bar ended up being 100% for 0.5% of the total execution time. That means 18 seconds on a 1 hour process.
- Fixed the comments to match the inner workings of RedrawFrequency.

First Symfony PR and second overall so hope I just did this the right way.

PR #8419 Rebased for 2.2
