Example 57: choose better example

The example is misleading as it places a percent-encoded string into a URL template that looks like an OData URL (parentheses and single quotes around the genreName), yet this would not result in a correct OData URL if the genreName would contain a single quote.

Better use a URL template with non-OData URL syntax, e.g.

http://host/someAPI/Genres/
