Host HTTP header was not propagated to the function because it is not

**What**
- When determining the service name of the function, remove any trailing
slashes, the slashes are not allowed in service names for either Swarm
or K8S, so this can only be a left over from the url path
**Why**
- This was preventing service resolution, and hence failed functions,
when the function was called with a trailing slash
Fixes#714

reinstates the behaviour through TDD - adding test coverage and
automated regression testing.
