VST3: Fix MSVC related crashes

Browse source 
Do not simply allocate std::vector<> space but also initialize
elements. The data is later accessed as C-pointer array: &var[0].
With most compilers simply reserving space in the vector is
sufficient in order to later access the elements directly.
However actually placing objects in the vector before referencing
them is more correct.
