Overlapping file updates, Office temporary files, macOS favorite

There was no 3.8.0 stable release since we had to release a 3.8.1-alpha first.
So 3.8.1 is the first stable release since 3.7.0.

Improvements for all users:

• When a change could not be applied on the other side, the document was not
  considered up-to-date anymore on the source side. This was fixed as part of
  the 3.8.0-beta.1 release.

Improvements for Windows users:

• Office temporary files should be effectively ignored since
  3.8.0-beta.1 too.

Improvements for macOS users:

• In macOS 10.13 (High Sierra), Apple removed the feature we were using to add
  the Cozy Drive directory to the Finder's favorite items. We had to find
  another way to bring it back. It should work as expected now.

Improvements for developers / contributors:

• One step less to build the app: yarn build:core is not needed anymore. If
  you were using yarn build, it should work the same as before. But now you
  won't have to rebuild in case of a core change before running the GUI.
  Less dependencies. Shorter stacktraces. This also fixed a few oddities.
• We also improved logs and jq filters.
