fix(ddl): MCOL-5974 TIMESTAMP columns are not IS NOT NULL by default in MCS ( #3670 )
...
The old behavior was to assign TIMESTAMP columns an IS NOT NULL
constraint if list of constraints was empty. Apparently, this particular
invariant was changed in 11.4 and bugfixes' mcol-5480.test started to
fail.
This patch fixes behavioral difference and reenables mcol-5480 test in
11.4.
