bug: unable to create a driver without the `app` capability

Summary

When creating a driver by passing a capability set without the app capability, the driver fails to be created and returns an error:

absolute_app_path invoked and app is not set! (ArgumentError)

Could not reproduce this using ruby_lib 15.2.0 and identical versions of ruby_lib_core. I believe the issue was likely introduced in #1037.

Environment

• Appium version (or git revision): 2.11.2
• ruby_lib version: 15.2.1
• Mobile platform/version/device under test: Android/iOS

Actual behaviour and steps to reproduce

Create a driver and pass a capability set that does NOT contain the app capability, e.g.

url = "http://localhost:4723/"
caps = {"platformName"=>"iOS", "appium:options"=>{"automationName"=>"XCUITest", "deviceName"=>"iPhone", "udid"=>"<udid>", "noReset"=>true, "forceAppLaunch"=>true, "bundleId"=>"<bundle id>"}}
$driver = Appium::Driver.new({ caps: caps, appium_lib: { server_url: url } })

This returns an error.

Expected behaviour

Driver is created fine

Yes, it looks like ruby_lib's historical place reason. Let me fix that.

Could you try out with 15.2.2?
