fix(tests): retarget the two tests master added onto logos-qt-host

Rebasing this branch onto master replayed the qt-host retarget over a
master that had meanwhile added test_logos_qml_bridge_deferred (#20) and
test_logos_qml_bridge_calls (#21). Both link
logos-qt-sdk::logos_qt_sdk, and the retarget commit never saw them, so
the textual auto-merge left them pointing at a target this repo no
longer imports. CMake failed the generate step outright:

  Target "test_logos_qml_bridge_calls" links to:
    logos-qt-sdk::logos_qt_sdk
  but the target was not found.

Retargeted to logos-qt-host::logos_qt_host, the same rename the other
eight executables already carry. Restoring the logos-qt-sdk input was
the wrong fix in the other direction: it would put a second copy of the
Qt host runtime back in the closure, which is what the retarget exists
to prevent. Both tests only include logos_api.h (now from qt-host) and
the protocol headers qt-host links PUBLIC, so nothing qt-sdk-only is
lost.
