TestL3GwModeMixin can fail randomly because it doesn't initialize core_plugin and can be run random core plugin depending on execution order of tests. It also fails with core plugin uninitialized when it is run without other tests. This patch refactors the setup code of core plugin and apply it to the related tests. This patch reveled the same bug of test_metaplugin.py which is also fixed by this patch. Closes-bug: #1273259 Change-Id: I3c1d4d8b3d69262b89c7747daa8267bf2c8e7f6b
