Revert "Fix compilation error against current master" This was a wrong fix as plugins cannot transitively depend on any gerrit core library, that itself transitively depends on substantial sub-graph of gerrit core. The correct fix is to export the the needed library in the Plugin API. This reverts commit 85a07f6a039cc5290b963bd42ebc2b33cd698cd4. Change-Id: I3579f1ceb9563bca02ebd441660cec6c8c0518e8
