Fix for MuonLayerHoughTool crash when running with VERBOSE output
Whilst debugging Muon CA/old-config differences, I ran into a crash in MuonLayerHoughTool with VERBOSE output.
This is because after debug.release(), calling get() returns nullptr. So I just reordered this code a little to avoid the crash. This should have no impact on production output.
Tested with q445 and MuonConfig and MuonCombinedConfig unit tests.
