[BUG]: geopackage writer overwrite functionality is not working when file is in use

[JohannaOtt]

Describe the bug
When exporting geopackage from hale»studio to an existing file with the "Overwrite target file if it exists" option enabled, the data is not overwritten but added if the file is in use (for example in QGIS)

To Reproduce
Steps to reproduce the behavior:

1. Export a geopackage from hale»studio
2. Load the geopackage for example in QGIS
3. Export the geopackage again from hale»studio to the same file with the "Overwrite target file if it exists" option enabled
4. Load the file again in QGIS. Every object will be contained twice.

Expected behavior
The export functionality should throw an error if it cannot overwrite the existing file instead of adding the data to the file again.

Additional context
If the file is not in use, the overwrite functionality is working as expected.
In this part of the code, it should be checked if the file can be overwritten, or not.
If not, the export function should throw an error.
