Bug: when there is more than one app with the same name the code breaks

[cormach]

When running connectapi::deploy(), the code fails when there is more than one app with the same name in the Posit Connect instance.

https://github.com/rstudio/connectapi/blob/main/R/content.R#L536

The error is

Error in eval(parse(text = text, keep.source = FALSE), envir) : 
  object 'to_content' not found
Calls: <Anonymous> -> content_ensure

The code currently references is as follows:

if (length(content) > 1) {
      stop(glue::glue(
        "Found {length(to_content)} content items ",
        "matching {name} on {connect$server}",
        ", content must have a unique name."
      ))

The problem occurs because to_content isn't defined
