fix: show more button missing when grouping tasks by project in tasks…

… tab EXO-72589  Meeds-io/meeds#2441 (#432) (#433)

prior to this change show more button was missing because of false value
check for "filter Active". 

after this change, the number of tasks in the retreived projects is counted and the show more button is displayed.
