MDL-59116 analytics: Multiple predictions for each analysable time range
Now we only predict using the most recent range available, this means
that if someone upgrades to moodle 3.4 at three quarters of a course
we will only calculate the latest range, previous ranges were not
displayed anyway once more recent predictions were available.
This commit deletes all previous predictions :) this shouldn't be a
problem in master as we don't provide any guarantee, the alternative
(retrive sampleids from mdl_files) would have been slow and a waste of
time as well as require horrible code in an upgrade step (text fields
do not accept defaults nor we can use NOTNULL).
