Import doesn't respect "Use md5 checksum" setting of tasks

[kaoneko]

• [x] I have read the above note

What version of Round Sync are you using (About -> App version)?

2.5.4

What is your Android version, phone model and manufacturer?

Android 13 / LineageOS 20 on Pixel 4a

Which steps are required to reproduce this issue?

When importing a Round Sync backup which has md5sum: true in the JSON of every task in rcx.json, all imported tasks will actually have Use md5 checksum disabled, and when you then export a new config backup, this is also reflected in the JSON.
