[Tracker] tracker-extract no longer (re)started on demand/crash?

Does a crashing tracker-extract cause tracker-store to be unavailable?
Shouldn't we restart tracker-extract if it crashes?
I remember one of the reasons moving the data extraction process into
a separate tool was to be more resilient.
