Removed reference to API version that was released.
Fix generated PHP namespace.

Generated PHP namespaces are all lowercase.
Added missing semi-colon to end of namespace.
Changed test service name from 'finding' to 'finding_api' as original
transform would have created the namespace Finding_api which would have
defeated the point in making the first letter a capital. By changing the
service name I hope to spot future errors like the above more quickly.
