BatchUpdates in SqlServer leads to 'table already exists' on temp tables that were dropped

[chrisknoll]

On pathway analyses with multiple Ts, the same analysis sql (with temp tables) is re-run and batch executed, but sql server will concatenate the statements, and then identify duplicated temp tables as 'already exists'.

The proposd fix is to indicate in CancelableJdbcTemplate that supportsBatchUpdate should return false for sql server.
