prevent inter-session dependencies

The problem was that the 'emptyness' of m_cookieForToken was used as an
indication that there was no response packet still in the air. However,
this hash was not reset after a debugging session was aborted using S-F5,
so it could contain items from a previous run, effectively preventing
automatic triggering of the necessary 'continue'.

Indexing both /include/Qt and /include/{QtCore,QtGui,...} makes the code completion with fedora.

Don't crash then
