CPA plugin/device crashes/breaks the program when initialized without setting pre-init parameters

Currently, due to a bug, TraceXpert doesn't set pre-init parameters when a previously created project is loaded. Because of this, it is not possible to load projects with the CPA plugin, because its init() method can't finish.

The m_traceLength, m_predictCount, m_order variables are not initialized, thus contain bogus values and claim huge amounts of memory as a result.
