disabled does not carry through to fileInput

Similar to #223, the disabled function does not get carried through to the nested button. The input itself is disabled, so nothing happens when you click it. But it's a bit deceptive to users to have a clickable button that is disabled.

library(shiny)

ui <- fluidPage(
  shinyjs::useShinyjs(),
  shinyjs::disabled(
    fileInput("testup", "testupload")
  )
)

server <- function(input, output, session) {}

shinyApp(ui, server)

Do you think it would work to cast the net a little wider and add span[btn] to the set of elements that are checked when enabling/disabling?

It took a little bit more to fix this, but it should work now. Thanks for the report.
