Match any url in SttpBackendStub

[klappenbach]

Currently (I think) the only way to match any url is using .whenRequestMatches(_.uri.path.nonEmpty).
A simpler option would be handy, something like:

implicit val testingBackend: SttpBackendStub[Future, Nothing] = SttpBackendStub(AkkaHttpBackend())
    .whenAnyRequest
    .thenRespond( ... )

or perhaps

implicit val testingBackend: SttpBackendStub[Future, Nothing] = SttpBackendStub(AkkaHttpBackend())
    .whenRequestMatches(any)
    .thenRespond( ... )

I suppose you can also do .whenRequestMatches(_ => true)?
