QNode: stop using hash<node,connection> for bookkeeping5.13

It is totally valid to have actually the same node used for 2 distinct
connections (e.g setting 2 different node properties to the same node).
With the hash, the second setter call would overwrite the first connection
resulting in leaving a dangling connection around potentially resulting in
crashes.

Instead use a QVector<pair<node, connection>> and adjust code accordingly.
