Author names not parsed correctly when entered as single character string

[annakrystalli]

Parsing of Author names onto templates doesn't work when they are not entered as Authors@R on DESCRIPTION.

Perhaps a function that processes the name and also incorporates #49 could work.

Ultimately though, this should be flagged as incorrect storing of author details at editor's checks/review.

Such checks could therefore be automated at this stage and a comment added to the editors.md/review.md during intitialisation. Perhaps such a function, that flags common errors that aren't picked up by check() and goodpractice could live in rodev() and print out an initial report as the first comments of any response template. Does this make sense @maelle ? Would love to hear your thoughts on this.
