get_dbpedia_uris() fails if argument retry is logical

[ChristophLeonhardt]

For dbpedia v0.1.2.9005 get_dbpedia_uris() will fail if the argument retry is logical (which it is by default). Then this line will result in an error because the object request is not found:

dbpedia/R/dbpedia.R

Line 392 in e3f3c41

request_max <- if (is.logical(retry)) as.integer(request) else retry

If retry is an integer value, then it will work. Using retry = 0L turns the functionality off which should be in line with the default behavior in prior versions.
