Duplicate sending

[Lomaiin]

Hi ! I found a little bug when using the app.
Btw, copyparty is really cool, thanks for that !

Describe the bug

Once a file has finished uploading, if the screen is rotated, the upload will start again.

To Reproduce

Upload one or more files. Once the 'Finished' menu pops up, rotate the screen and the upload will start again.

Expected behavior

Once the upload is finished, do not upload again when the screen rotates.

Client details

if the issue is possibly on the client-side, then mention some of the following:

• the device type and model: Xiaomi Poco F4
• OS version: Android 14 UKQ1.231207.002
• party-up version: 1.7.0
• party-up on upload success: Show menu (default)
