Issue

• Some offline operations were not processed correctly, such as renaming the same file twice, or renaming and then deleting it.
• Files uploaded into a folder created offline could get a wrong path.
• Offline uploads used the wrong modified and creation time.
• The conflict dialog was not shown properly and showed wrong server file data and a wrong label.
• After resolving a conflict, the file list was not updated until a manual refresh.
• An offline version could be lost silently when the folder synced before the conflict was resolved.
• Notifications stayed even after the offline operation was handled, so users had to remove them manually.

Changes

• Fixes offline operation logic (create, rename, delete, operations inside folders)
• Keeps pending items until they are created on the server
• Fixes refresh mechanism after offline operations complete
• Fixes notification handling and pending intent action
• Fixes the conflict resolve dialog for offline operations, such as showing correct data, dismissing and showing the dialog
• Uses ClientRepository instead of ClientFactory in the offline operations worker
• Handles edge cases

How to test?

1. Create a folder and upload a file, turn off the internet, then upload a different file with the same name to cause a conflict. Turn the internet on, open the notification and choose "Keep both". Both files should appear without a refresh.
2. Turn off the internet and rename the same file twice. Turn it on; the file should have the last name.
3. Turn off the internet, rename a file and then delete it. Turn it on; the file should be deleted.
4. Turn off the internet, create a folder, upload a file into it, then rename the folder. Turn it on; both should be created with the new name.
5. Turn off the internet and delete a folder. Turn it on; the folder should be deleted without error notifications.
