Test warnings and failures

[Michał Bojanowski]

Warnings seem to be related to some deprecated testthat functions.

Error comes from

tergm/tests/testthat/helper-CMLE.R

Line 213 in 15d8d2d

 expect_true(z.error(form.mle(y0,y1,y2m), coef(fit)[1], vcov(fit, sources="estimation")[1,1]) <= tolerance) 

which should be TRUE but comes out FALSE.
