[JENKINS-52768] echo step should use toString

The echo command requires a String or GString to be passed to it (perhaps CharSequence?), and it fails with an obscure error about not having an @​DataBoundConstructor otherwise.

Instead, the usual API for some sort of print(Object) is to use toString(), and the echo command should invoke Object#toString() if it gets an argument that it doesn't recognize.
