Remove commits in RETRY status from report.html
Remove commits in RETRY status from report.html

When a commit goes to the RETRY status, there will be more than a
single entry for the same commit_hash. When the commit build
eventually succeeds, the generated report.html looks confusing,
because the repo and build log links for the RETRY build point to
the successful one.

This commits hides commits in RETRY status from report.html, while
keeping them in the database and in status_report.html. The main
advantages of this are:

- Remove confusing information
- Allow gathering statistics for failed builds due to known errors.
- Keep commits in RETRY status in status_report.hmtl, in case it is
being checked while retrying.
