Switch to existing document in new tab by default
requested to merge ngraham/okular:switch-to-existing-document-if-already-open-by-default into release/21.04
Right now Okular defaults to opening an already-open document in a new tab when opened a second time, which is a bit odd. Most other document-based apps will switch to the existing document's instance instead of opening a new instance of it.
Interestingly enough, Okular has an option to do this, but it's off by default. I think on by default makes more sense here, to be consistent with other document-based apps. Since the option exists, people who have a specialized use case that commonly involves opening multiple instances of the same document can toggle the option to have that. Everyone wins!

cc @teams/vdg and @niccolove in particular for the consistency angle
