Subject: [PATCH] DolphinView: display errorMessage when copy errors occurs

when copying multiple files.

CopyJob skip those by default (CopyJobPrivate::slotSubError), and emits warning.
Hook this to errorMessage.

We would need to improve this as only the last error Message will be
visible.

BUG: 506282
