Improve sync speed and updated dep. versions

Improved sync speed by resolving the N+1 query issues.
Solves #1402 and Solves #1453

With this change there is just one query done to retreive all the
important data, and matching is done in-code/memory.

With a very large database the sync time went down about 3 times.

Also updated misc crates and Github Actions versions.
