get_publications() pubid outputs all <NA>

[dirtyplants]

First, thanks for maintaining this package!

I am having some trouble getting any pubid to show up in output of get_publications(). For example:

> scholar::get_publications("9zQR3rsAAAAJ")$pubid

[1] <NA> <NA> <NA> <NA> <NA> <NA> <NA> <NA> <NA> <NA> <NA> <NA> 
[...]
[201] <NA> <NA> <NA> <NA> <NA> <NA> <NA>
Levels: 

If you or someone else can reproduce the error, perhaps something is wrong here or just below (else, I may have a unique or self-made problem):

scholar/R/publications.r

Line 87 in 5a5e041

pubid <- cites %>% html_nodes(".gsc_a_at") %>%

It causes some downstream code to fail, because it is impossible to access values for pid in get_complete_authors(), for example.

I inadvertently duplicated this (and closed the present issue): #103 (comment) FYI: This is concerning scholar v0.2.2.
