MDL-69973 xmldb: Fix problem with MariaDB >= 10.2.7 metadata defaults

Browse source 
With MariaDB 10.2.7 the driver was incorrectly returning '' (empty
string) as default for all the columns having null (meaning, no
default).

Also, cover the case in unit tests, it seems that we were already
testing other defaults but not the null case.
