Describe the Bug

Floccus creates a new lock file on every sync and doesn't delete it after the sync completes successfully. Over the time these files accumulate. The naming scheme is bookmarks.xbel (n).lock where n increments on each sync.

This behavior exists for more than a year, I just happen to notice it now (I had thousands of lockfile remnants in my webdav storage). Also this issue exists in bot the android app and the firefox desktop browser extension

Expected Behavior

Only a single lockfile shall be created which is also supposed to disappear after the sync completed successfully

To Reproduce

• Use mailbox webdav storage
• sync
