Code Lens function references shouldn't include the function definition

[mattmcnabb]

The new feature in v1.3.0 displays any references in a workspace for functions. These references always have a count of at least 1 because it includes the function definition in the references. Please consider referencing only the calls to the defined function, not the definition itself. This offers a more useful count.

Good catch! I'll get it fixed in the next release.
