FMU is not re-initialized after set continuous state

[Jens Frenkel]

After setting a state using the function
fmiSetContinuousStates

the fmu is not re-initialised.

see also the spec.

<pre>fmiStatus fmiSetContinuousStates(fmiComponent c, const fmiReal x[], size?t nx);

Set a new (continuous) state vector and re-initialize caching of variables that depend on the states. Argument nx is the length of vector x and is provided for checking purposes (variables that depend solely on constants, parameters, time, and inputs need not to be newly computed in the sequel, but the previously computed values can be reused). Note, fmiEventUpdate might change the continuous states as well. Note: fmiStatus = fmiDiscard is possible.</pre>
