Correctly catch InstanceExists in servers create API

When osapi_compute_unique_server_name_scope is set to project
or global an attempt to create a server with a name which
already exists results in an InstanceExists exception being raised.
This was not being handled in the API layer causing a 500
status error code. This patch fixes it so the exception is caught
correctly and a 409 Conflict is returned instead
