Prior to this commit, if an SQLException was thrown while retrieving column metadata from the database, SimpleJdbcInsert would generate an INSERT statement that was syntactically valid but missing columns, which could lead to data silently missing in the database (for nullable columns). This commit fixes this by clearing all collected column metadata if an SQLException is thrown while processing the metadata. The result is that an InvalidDataAccessApiUsageException will be thrown later while generating the INSERT statement. The exception message now contains an additional hint to make use of SimpleJdbcInsert#usingColumns() in order to ensure that all required columns are included in the generated INSERT statement. SimpleJdbcCall can also encounter an SQLException while retrieving column metadata for a stored procedure/function, but an exception is not thrown since a later invocation of the stored procedure/function will likely fail anyway due to missing arguments. Consequently, this commit only improves the warning level log message by including a hint to make use of SimpleJdbcCall#addDeclaredParameter(). Closes gh-26486
