Fix warning that crops up when using chk_text_nmiss

[kinto-b]

x <- testdat::chk_nmiss(mtcars$vs)
#> Warning: `chk_nmiss()` is soft-deprecated as of testdat 0.1.0. Use `chk_text_nmiss()` instead.
#> This warning is displayed once per session.

We just need to replace chk_nmiss() with chk_text_nmiss() in the definition of chk_text_nmiss()

testdat/R/chk.R

Lines 64 to 68 in 9f3ef72

	#' @rdname chk-generic
	#' @export
	chk_text_nmiss <- function(x, miss = getOption("testdat.miss_text")) {
	!chk_miss(x, miss)
	}

Yo!

Yeah the deprecation message is correct, just needs to point to !chk_text_miss(x, miss) instead (my bad!)
