MDL-43682 log: Fix issues with log report

Following fixes have been made:-
Porfile links where generating errors when there was no courseid present. Fixed the same.
get_readers() method was accessing an undefined property.
popups were used for action and ip address before the whole rewrite, we should maintain the same behaviour.
Fixed string issues.
