`hasFun` cannot find `jobRunScript` besause is called differently in `tools:rstudio`

[netique]

The package exports function rstudioapi::jobRunScript(), but when I want to check if such a function is available, RStudio issues a false negative. It is because the function is in fact called runScriptJob and hasFun() checks for paste0(".rs.api." + name) in tools:rstudio environment.
