Populate project listbox with all owned projects when projectowner textbox is emptyRemove depending on projectOwner field in SCMHeads
Populate project listbox with all owned projects when projectowner textbox is empty.This is a minor UI improvement but needs a lot of work to be done since all SCMHeads depend on the projectOwner field and it is complicated to get rid of that field. We simply need to use the `project` listbox field. It needs to be planned how to do it. One attempt to do didn't work as expected. Take some inspiration from ArgelBargel's GitLab BS.
