[R-pkg-team] Bug#915717: Some bioconductor packages FTBFS because of missing 'git_branch' field

[Dylan Aïssi]

Package: dh-r
Version: 20181123
Severity: important

Some bioconductor packages (r-bioc-genomeinfodbdata and r-bioc-go.db)
FTBFS because of missing 'git_branch' field in the DESCRIPTION file.
This need to be clarified with upstream. But, at the same time, we can
relax the requirement of this field for these packages. i.e. switch
the 'die' at line 249 by a 'say'.
