MDL-47706 gradebook: Update pageload time between changes

Since MDL-38732 we reject changes if another change has been made more
recently. As a result, if process_data is called, and then we roll into the
next millisecond period before process_data is called again, the change is
rejected.

Different errors were seen because the millisecond rollover occurred at
different time within the test.

Different error conditions were seen because not all of the tests check for
an error from the call to process_data(), instead just checking that the
value had been updated correctly.

get right.

MDL-47762 gradereport_user: Hide contribution and weights when relevant

The contribution and weight columns should be hidden when the course
total is because they can be used to compute the hidden course total.
