Clips are placed on timeline when added to project bin if the contextual menu was opened on timeline previously
closing this https://invent.kde.org/multimedia/kdenlive/-/work_items/2184
and this https://invent.kde.org/multimedia/kdenlive/-/work_items/2185
because this is not related to pictures or texts... but to avery kind of item.
to reproduce: just open right mouse menu on timeline, move the mouse to project bin and create a clip. the clip is placed automatically on last position of mouse on timeline (with a right mouse pressed)

using latest nightly build on windows, not tried on linux.
i found "orphan" clips in random spots after rendering because of this.
