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.
This commit only contains calls that were automatically converted with clazy.
Use qCInfo for anything that has general value for support and
development. Use qCWarning for any recoverable error and qCCritical
for anything that could result in data loss or would identify a serious
issue with the code.
Issue #5647
This gives more insight about the logs and allow setting fine-tuned
logging rules. The categories are set to only output Info by default
so this allows us to provide more concise logging while keeping the
ability to extract more information for a specific category when
developping or debugging customer issues.
Issue #5647
The backtrace seems to indicate that the account is invalid.
I don't know how this can happen, maybe the account's display
name was changed while the app is running?

My theory is that the AccountState stored in a property of the job was destroyed.
before the job timed out.
Therefore, the qobject_cast within the qvariant_cast would call the metaObject()
virtual function on a dangling pointer.
Fix it by storing a QPointer instead which will track the deletion.
