catbref e00579e1a2 Fix incorrect LatestATStates SQL table definition
This table was previously defined using the TEMPORARY keyword as the rows were used as a cached/index to speed up AT trimming SQL statements.

However, the table definition was lacking the "ON COMMIT PRESERVE ROWS" clause, and possibly the "GLOBAL" keyword, which caused the table contents to be emptied, immediately after being filled, when <tt>repository.saveChanges()</tt> was called (i.e. "COMMIT").

This caused latest AT states to be trimmed in error.

AtRepositoryTests.testGetLatestATStatePostTrimming also fixed so that it fails with the previous, broken code.
