Who could know that a removed package could make such a mess? :)

Thanks for the suggestion! Adding such Breaks solves most of the problems.
When I run “apt dist-upgrade”, apt no longer tries to remove libqt5gui5.
When I was testing this, I tried to upgrade only a subset of packages using
“apt install libqt5widgets5” (that package was installed, but running
that command should upgrade all Qt packages). Unfortunately, when running
this specific command, apt still wants to remove libqt5gui5 and install
libqt5gui5-gles. But I think we can live with it, as most users who have
not upgraded yet will probably use dist-upgrade (or full-upgrade).

To be more precise, it is a problem for users of sid and testing who have
not upgraded for a long time. Users of stable should be safe. Things are
a bit worse in Ubuntu, where the bad qt5-default made it to a stable
release. In any case, I discussed with my co-maintainer (Lisandro) and we
don't want to readd qt5-default.
