Acid runtime error

To store test logs on the server, I updated the BuildReports and PkgBuildReports datatype. Everything is working well except from migration. The server can't start with old state files, and gave the following error:

I can't find where I've done the migration wrong. Code is in branch test-log. Relevant file should be src/Distribution/Server/Features/BuildReports/BuildReports.hs.
