patched t/ tests in line with recent app changes

modified HMRN previous diagnoses list to only skip previous ICDO3 diagnoses if /3 or MGUS (not other /1 or /6); HMRN previous diagnosis list can retrieve records based on record id or patient.id; changed query_modifiers to an array instead of str in site/lab_number.tt; print report only highlights diagnosis if modified AFTER authorisation date

buxfix to print_run calculation of end_date - subtracted 1 min instead of 1 sec, so any relevant change to report in last minute of day would be ignored; added total count hidden field to print_run to allow calculation of last 'next 50' link

minor bugfix to C::Chart::hiv() calculation of results - case-insensitive to accomodate legecy data; added 'next 50' link to print run output

modified print_run to get initial calculation of total number of records requested, then present a list of smaller print runs if max print run size exceeded
