Fixed

• Validate application environment sources so nil values and empty strings are not valid app environments. Symbols are now always cast to a String before set as the application environment.

  Ruby

  # These will no longer be accepted as valid app environments
  Appsignal.configure("")
  Appsignal.configure(" ")

• Fix Capistrano version 2 and 3 support when using an appsignal.rb config file. It will now pick up the config from appsignal.rb file.
