Serverless Application Conditional Creation

[bbernays]

Description:
It seems that Conditional attribute is not being respected for AWS::Serverless::Application

Steps to reproduce the issue:

1. Define AWS::Serverless::Application pointing to non-public application in us-east-2
2. Add conditional statement that evaluates to False
3. run sam build --region us-west-2

Observed result:
I get the following error:
samcli.commands.validate.lib.exceptions.InvalidSamDocumentException: [InvalidResourceException('<APPLICATION NAME>', 'Application with id arn:aws:serverlessrepo:us-east-2:<ACCOUNT>:applications/<APPLICATION NAME> could not be found.')] ('<APPLICATION NAME>', 'Application with id arn:aws:serverlessrepo:us-east-2:<ACCOUNT>:applications/<APPLICATION NAME> could not be found.')

Expected result:
The expected result would be for the application to be ignored and not built

How is your conditional statement defined? Is it based on Intrinsics?
