corrected ClassId.isAccessibleFrom behavior on arrays #743

[volivan239]

Description

ClassId.isAccessibleFrom didn't work correctly on arrays (sometimes returned false when it should have returned true), which lead to unnecessary usage of refelction and bugs in generated tests.

Now this method returns true on array iff contained elements' class is accessible.

Fixes #743
