Fix crash when trip info changes across remember/restore tree state

Interesting crash. Importing a file gets us to a stage where we have a
trip tree note with a date that doesn't exist as trip date. That's clearly
bogus. And in import_files() we assume that all is still fine and try to
restore the old expanded / selected state for the various trips.

There is clearly a bigger issue here, this patch at least prevents the
actual crash from happening by making sure the pointer is non-NULL before
dereferencing it.
