use get application API when calling get_rstudio_app_info

[mslynch]

Intent

Resolves #464.

Type of Change

• Bug Fix
• New Feature
• Breaking Change

Approach

With shinyapps.io, app_id will be an application id in get_rstudio_app_info, so we need to use the GET application API.

Automated Tests

Directions for Reviewers

1. Ensure the rsconnect-python folder is gone: rm -rf ./my-shiny-app/rsconnect-python
2. Deploy to shinyapps.io: rsconnect deploy shiny --name $YOUR_CRED_NAME ./my-shiny-app/
3. Redeploy to shinyapps.io: rsconnect deploy shiny --app-id $YOUR_APP_ID --name $YOUR_CRED_NAME ./my-shiny-app/
