DESCRIPTION without Depends

[muschellij2]

Related to #114. If you don't have Depends, then dockerfile breaks:

library(desc)
library(containerit)
desc = description$new("!new")
desc$set("Package", "foobar")
desc$set(Title = "Example Package for 'description'")
desc$set(Description = "Example Package for 'description'.")
desc$set_dep("dplyr")
desc$set_dep("tidyr", "Suggests")
desc$set("License" = "GPL-2")
desc$del("Maintainer")
desc$del("BugReports")
desc$del("URL")
tdir = tempfile()
dir.create(tdir)
tfile = file.path(tdir, "DESCRIPTION")
desc
#> Package: foobar
#> Title: Example Package for 'description'
#> Version: 1.0.0
#> Authors@R (parsed):

desc$write(file = tfile)
dx = dockerfile(from = tfile)
#> Error in val %||% default: Field 'Depends' not found
