McuSupport: Add workaround for CodeModel/SymanticsChecker race condition

Currently it can happen that some qml files will not be picked in the
CodeModel Snapshot when the Semantic Checks are performed resulting in
wrong errors in the code editor QTCREATORBUG-29269
Triggering QmlJS ResetModel fix the errors.

This change will make triggering the Reset automatic.
