gitlab: fix page number check

The current page number was being manually set to =1 in the beginning of the
count to avoid a infinite loop, but it isn't necessary, considering
go-gitlab offers the "CurrentPage" information from the API response object.
This patch checks for the library's struct member instead of forcing a magic
assignament.
