fix func names to fix build of gonstructor

[kovetskiy]

Currently gonstructor has compilation errors:

# github.com/moznion/gonstructor/internal/constructor
../../internal/constructor/all_args_constructor_generator.go:26:32: funcSignature.AddFuncParameters undefined (type *generator.FuncSignature has no field or method AddFuncParameters)
../../internal/constructor/builder_constructor_generator.go:44:56: generator.NewFuncSignature(strcase.ToCamel(field.FieldName)).AddFuncParameters undefined (type *generator.FuncSignature has no field or method AddFuncParameters)

and after fixing it you could get

# github.com/moznion/gonstructor/cmd/gonstructor
cmd/gonstructor/gonstructor.go:102:23: rootStmt.EnableGoimports undefined (type *generator.Root has no field or method EnableGoimports)

@moznion Hi! Could you please take a look at the PR because currently gonstructor's master branch doesn't work 😢

@moznion hi, I have similar problem.

I'm sorry for the late reply and I appreciate your patience.

This issue because gonstructor uses older gowrtr (i.e. v1.0.0) so the method signatures were not compatible with the latest ones.
gonstructor's code has just followed the latest gowrtr so it would be able to compile certainly (ref: moznion/gonstructor@f712621).

(And, go vendoring mechanism doesn't allow to use v2 as a version specifier; therefore, I've re-versioned those that have v2 version to v1.x.x )

@kovetskiy Once you confirmed the problem has been solved, could you please close this issue?
