Your ec2_instance_tag 'name:webserver' is being evaluated as a string
because there's no space, it needs to be a YAML dictionary.
If you read the docs on the module (ansible-doc ec2), they state:
- instance_tags
> *a hash/dictionary of tags* to add to the new instance or for
> starting/stopping instance by tag; '{"key":"value"}' and
> '{"key":"value","key":"value"}'
> [Default: None]
> version_added: 1.0

And if you pay attention to:
http://docs.ansible.com/ansible/latest/reference_appendices/YAMLSyntax.html
* A dictionary is represented in a simple key: value form (the colon must
> be followed by a space): *
>
You have:
ec2_instance_tag:
name:webserver
This should be:
ec2_instance_tag:
name: webserver
