Missing parameter names in interface methods

[kinbiko]

Did

Copied the following struct:

type foobar interface {
    baz(context.Context, int)
}

and ran mokku, and pasted the result.

Expected

A mock struct that compiles.

Got

A compile error, because the resulting mocked method attempts to pass context as a parameter to the underlying Func.

Suggestion

In the case that parameters are not named, we should create a dummy variable name.
a,b, etc is probably fine for unnamed parameters. If users have more than 26 variable names then, well... there are bigger design issues at hand.
