Release v3.20.0-beta.2 (#1852)

Improvements for all users:

- We've found out that the synchronization process could be started
  more than once. Although this should have no effect (i.e. one start
  replacing the previous one) we've made sure we only start the
  process once. This should avoid wasting some resources in an
  extraneous start.
- In some situations, when moving a file or folder and overwriting an
  existing document, the local file system can fire a move event
  without firing a deletion event for the document that's being
  overwritten. We were very conservative in the way to we treat
  changes that could erase content so we would generate a conflict for
  those moves.
  Now that we have file versioning on the Cozy, we feel comfortable
  accepting those changes and will thus delete the overwritten
  document but will keep its existing references (e.g. photos album,
  bills…) and add them to the document being moved.

Improvements for Windows and macOS users:

- To avoid synchronizing temporary documents generated by some
  software when saving a new version of a document, we maintain a list
  of file name patterns that should not be synchronized. We had some
  patterns for the Microsoft Office suite files but we did not account
  for temporary files generated for all the file types those can open
  like Open Documents.
  We've enlarged the pattern used to match those files those that all
  temporary files created by the MS Office software should be matched
  and thus not be synchronized.

Improvements for Windows users:

- We've got reports from users experiencing app crashes. In at least
  some of those cases, the anti-virus seems to be involved.
  We've implemented some mitigations as found in the Electron
  documentation and hope to see those issues resolved.
