Jacob Mathew 0b52b28b91 MDEV-10355 Weird error message upon CREATE TABLE with DEFAULT 
Fixed handling of default values with cached temporal functions so that the
CREATE TABLE statement now succeeds.
Fixed virtual column session cleanup.
Fixed the error message.
Added quoting of date/time values in cases when this was omitted.
Added a test case in default.test.
Updated test result files.
