The class loader delegation in wires was not correctly working when a module
imported a packaged that was an aggregated (via require-bundle) export from
another bundle. The wire for the package should have been delegating to the
module and instead it was delegating directly to the module content, which
did not account for the wires of the aggregated split package. (FELIX-722)
