db:add tab/col name validation to common functions

No error thrown in common_sp functions in case column or table does not
exists.

This patch adds validations to drop/change type/rename column common
functions in order to prevent the setup continue in case that there was
an error in the table/column name.

This patch also fix some upgrade scripts that used invalid/non-existing
column names.
