Tk background window doesn't destroy.

[dat-adi]

Describe the bug
In location_designator.py, the window for the GUI folder location selection is prompted from the tkinter module, which initializes a root window for itself.
The problem lies where it has to be manually close even after selecting the location of the folder.
Withdraw works to hide it, but, the window runs in a loop even so.

To Reproduce
Steps to reproduce the behavior:

1. Go to adding_tickets.py
2. Run the program.
3. You can immediately see the root tk window in the background.
4. Select your folder/storage location, and hit continue, and see that the root window still remains.
5. Has to be manually closed even after the adding ticket window closes.

Expected behavior
The tkinter root window should not be seen, and must close on it's own after the selection of the location is done.

Alternatives
Maybe we could add in a button in the adding_tickets.py tkinter window, to prompt a tkinter filedialog to configure the location of the db in.
