Fix tests in core/tests-arquillian so that only packages exported by the weld osgi bundle is used

While trying to run the Weld arquillian tests against remote GlassFish, it was found out that some of the tests were failing against GlassFish, because some Weld packages are not being exported by the weld-osgi-bundle (see analysis and the suggested additional packages to be exported in http://glassfish.dev.java.net/issues/show_bug.cgi?id=13713).

Pete's suggestion was to fix the tests to not refer to these classes/packages rather than export them from weld.

Please find attached a rough initial list of tests that would need to be modified and their references to the additional packages that are not exported by weld-osgi-bundle.
