Issues found during testing :

• If I export a theme and import it again -> error since the name already exists (OK) but if I change the name in the file and try to import it again, nothing happens, I need to navigate or refresh the page.
• The url of settings is changed with params from themes query

Minor issues

• Ordering of themes seem random, shouldn't we order by name or creation date ?

@SouadHadjiat
The different feedbacks have been addressed, now:

• the url should not be modified with the filters params
• importing a same file is a limitation from the browsers, I added a workaround that should empty the input file, so you can re-import the same file, it should work now,
• the themes are now ordered by creation date
