The R checks for CoxPH fail with survival package 2.39.2

[lckarssen]

The R checks for Cox' proportional hazards model (run_R_test_pacoxph) fail with version 2.39.2 of the R survival package:

This is on the current HEAD of master (commit 6d23885), but also for ProbABEL v0.4.5. On the Jenkins server the tests pass, the version number of the survival package there is 2.38.3.

Since the checks pass with Survival v2.38.3, I have moved the milestone from v0.5.0 to v1.0.0, so that this issue doesn't delay the release of v0.5.0.
