This is motivated by the fact that QMetaObject::noralizeSignature takes 7.35%
CPU of the LargeSyncBench. (Mostly from ABstractNetworkJob::setupConnections and
PropagateUploadFileV1::startNextChunk). It could be fixed by using normalized
signature in the connection statement, but i tought it was a good oportunity
to modernize the code.

The problem was that Share could be deleted *before*
the OcsShareJob itself finished. Since Share was the
parent of the network job, its object would be deleted
too early.
In general, it's unnecessary to assign parents to the OcsJobs
because they delete themselves when finished.
