Completion not working before close parenthesis

[renkun-ken]

Consider the following code

fun <- function(x, y, z) {
  paste0(x, y, z)
}

fun("free"|)

Inserting , at | does not trigger the signature help of fun(x, y, z), and typing e.g. z does not get any completion item. However, no error is observed from the logging of languageserver. Also, replacing "free" to some other strings, the problem might disappear.

It sounds that the issue is the detection of string enclosure.

I revert #276 and it works as before. Therefore, it is certainly caused by a regression in #276.

Thanks for the investigation. I'll take a look.
