Bugfix Release

Changes from v4.1.2:

Breaking changes:

• Fixed filtering google contacts by id instead of label name (thx to @PerfectSlayer for raising this bug).
  Check your .env file: You should use label names instead of ids for the variables GOOGLE_LABELS_INCLUDE and GOOGLE_LABELS_EXCLUDE. If you are using ids (e.g. 1c87d0118e225be5) you need to update them to the corresponding label name. If you are not using those variables, theres no action needed.

Bugfixes:

• Fixed an issue where the google contact filtering by label has been ignored (thx to @PerfectSlayer for the fix!).
• Updated setup document.
• Improved error logging
• Added api retries to avoid temporary errors
