QML UI: don't combine multiple trips to the same location into one

The way sectioning of the dive list works is by watching for different strings
in the section.property. In order to be able to tell different trips apart we
combine the address of the dive trip variable with the location (which will
create a new section for a new trip, even if the location text is the same) and
then strip that information out before showing the trip header.
