This commit fixes a bug with table duplication in mailing template:
- Click on a snippet with two columns
- Duplicate it
-> the snippet is duplicated but the two columns are transformed in two
rows.
This was because there is an implemented behavior for column
duplication: if we duplicate a column which was alone on its row, we
duplicate the row instead. This code should however be triggered when
duplicating the column alone to be working, not the snippet that
contains it.
Note: this required a backport of a33ec972ab
which was fixing a non-critical "bug" for 11.0. This non-critical "bug" is
therefor fixed here too.
