Fix retrieval of temporary table's column information

[aidanharan]

This PR fixes an issue with inserting into temporary tables (#1307).

Temporary tables names start with the # character. The issue was happening because we were retrieving the temporary table's column information from the normal database rather than the TEMPDB database.

SQL Server does not store the temporary table name as it is given. For example, the #temp_users table might be stored in the TEMPDB..objects table's name column as #temp_users_________________________________________________________________________________________________________00000000000B. To get around this the column_definitions_sql query has been updated to use the Object_ID column instead.
