fix(managerclient): improve post-restore repair progress display (#4083)

Previously all run/task properties of post-restore repair progress
were taken directly from the restore progress.
This included things like start/end time, properties,
status, cause and others. It resulted in misleading progress display.
This commit fixes that by deliberately leaving out, inheriting,
or setting interesting repair progress fields.

Fixes #4046
