BEAM loader: Fix bug that allowed loading of more than two versions
In commit b67d3e5447f4b2bca3ed92f3db84adb3f79f9b16 (which cleaned up handling of error reasons), the test of the return value from beam_make_current_old() in insert_new_code() was not updated, which meant that it never was true and any number of versions of code could be loaded for a module.
