QScriptDebuggerBackend crash fix.

QScriptDebuggerBackend::contextCount() method was trying to count
number of context push & pop and result was not equal to elements count
in QScriptDebuggerBackend::contextIds() list. Patch change
QScriptDebuggerBackend::contextCount() to call count() on ids list.
