Fix range v3 deprecation warnings
This fixes deprecation warnings in the clang builds when building against range::v3 version 0.9, which will become the default in the next LCG release.
This should have no effect at all on gcc builds and the ci-test
I am taking the liberty of adding lhcb-lcg-dev4 label, if successful the LHCb x86_64-centos7-clang8-* and Rec x86_64-centos7-clang8-dbg builds in that slot should have many less compilation warnings
This MR is independent of Rec!1843 (merged) but can be tested in the same ci-test
