Avoid meaningless logging and patching

[nolar]

Less patching, less logging when not needed.

Issue : #1234 (only if appropriate)

Description

Skip logging the empty diffs. They are useless. Especially on the resuming events, when the object is not changed actually. — As they are already skipped for the creation/deletion events, when the diff is a full-body vs. None diff.

Skip patching the body essence if it is the same as the one already stored on the object. This pollutes the logs with difficult-to-read JSON dumps, especially on the resuming events — when these patches and logs contain no useful information.

Skip purging the handler progress if there is no progress stored (e.g. for one-handler cases, when it succeeds immediately). This produced unnecessary API patches, and polluted the logs for no good reason.

These changes will reduce the amount of meaningless logs produced.
