Implemented workaround for issue that ParsePush was erroneously considered as unused and stripped out by the VM during iOS compilation. This results in a compiler error when building the iOS native code.

See https://groups.google.com/d/msg/codenameone-discussions/r1svrNwVOA8/6d1QmMVfBQAJ for more information on the problem.
