Set package version to 1.5

[PavelBal]

Builds were having the old version.

I don't see why the build is failing?

[Yuri05]

according to the build log: because the covr package is missing. The coverage is done separately by the GH action, so you can completely remove

on_success:
  - Rscript -e "covr::codecov()"

and also remove - Rscript -e "install.packages('covr', repos = 'http://cran.us.r-project.org', type = 'source')" from appveyor.yml

[Yuri05]

would also suggest to switch to the binary packages installation in appveyor.yml via R_PKGTYPE: binary (compare https://github.com/Open-Systems-Pharmacology/OSPSuite-R/blob/f621ced968a2f7cf83529118eea9f9f088d17da1/appveyor.yml#L32 ) In this build compilation of some source package which is prerec for covr is failed (for whatever reason, that's why covr was not installed)
