fix(ddl): MCOL-5974 TIMESTAMP columns are not IS NOT NULL by default in MCS (#3670)

Browse Source 
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.
