Where columns were previously of type `TYPE_INTEGER` or `TYPE_FLOAT`
but did not provide numeric data on output, we should change their
type to `TYPE_TEXT` (i.e. the default) to ensure that future work on
numeric aggregation doesn't affect them.
This is basically just bringing back the same check done prior to
MDL-79270 where if there is no data being returned the default value for
the accessctr would be "allow".
This ensures compliance with the following WCAG criterion:
"H71: Providing a description for groups of form controls using fieldset
and legend elements".
Use in the new browse users system report, to which it is quite
specific. The filter itself is a like for like replacement of the
pre-existing filter on the same page, and is really a combination
of existing role/category/course filters.
- The report 'Browse list of users' has been converted to use Report
Builder.
- Behat tests have been fixed and some test have been deleted for not
being relevant anymore.
Update existing entity to define remaining report elements. Add new
report source joining the entity to the user entity to provide data
for the reportbuilder editor.
