Store and restore active-project-path explicitly (#1472)

* Add "active-project-path" setting.

* Sync with GitManager and ProjectChooserButton

* Dont change active project just because a document changes

* Remove some unused code relating to active_project

* Do not override active project with default on startup

* Show global search dialog if scope unspecified

* Distinguish global search path from default action target

* Allow global search when no active project

* Set active project after load folder is none already set

* FileView: Use git_manager property

* Allow no project to be restored. Only user sets active project.

* On close other folders make remaining active

* Set active project context menu item for git repos

* Do not signal project-chosen twice for each change

* Do not call same code twice for each time a tab closes

* ProjectChooser: signal only on manual change

* Update popover only when activated;

* Remove debug code
