Changing "type* name" to "type *name" sometimes crashes shiboken

When adjusting spaces after pointer variables globally, I ran into the
problem that shiboken crashed when I tried to change

    QByteArray* cppSelf = %CONVERTTOCPP[QByteArray *](obj);

to

    QByteArray *cppSelf = %CONVERTTOCPP[QByteArray *](obj);

The temporary work-around was to add another space, resulting in

    QByteArray * cppSelf = %CONVERTTOCPP[QByteArray *](obj);
    //XXX      /|\ omitting this space crashes shiboken!

Assert (sources/shiboken2/generator/shiboken2/shibokengenerator.cpp:2048):

 message "Types of receiver variable ('QTimer') and %CONVERTTOCPP type system variable ('QTimer *') differ." QString

The regex CONVERTTOCPP_REGEX at sources/shiboken2/generator/shiboken2/shibokengenerator.cpp:152 would have to be fixed to capture this correctly.
