refactoring tests and merging test files

[schochastics]

A catch all issue to keep track of which tests have been refactored/merged.

The Goal is to have one test file per R file at the end

test files without a corresponding R file (main branch, not considering unmerged PRs):

setwd("~/git/R_packages/rigraph/")
Rfiles <- list.files("R")
testfiles <- list.files("tests/testthat/",pattern = "test-*")
tested <- testfiles |> stringr::str_remove("^test-")

cat(testfiles[!tested%in%Rfiles],sep = "\n")
length(testfiles[!tested%in%Rfiles])
