C++: fix scope matching for templates in FindUsages

When the cursor is on the name of declaration of a templated function,
then since f93758b8

 the scope returned
by Document::findScopeAt is the scope of the template declaration.
Before it was the parent scope of the template declaration.

The check in FindUsages::checkCandidates did not check all combinations
of template(-child symbol) scopes for the searched symbol and its
