[webui] Fix sorting in job history table

- Disable sorting in first (Revision) and last column.
- Enable sorting by default with "Time" column, descending.
- Fix sorting by "Time" column.
- Also fix sorting in "Build time" column.
- Prevent searching for the introduced hidden columns with no formatted
data.

This should fix #3986.
