fix: didn't use alias when importing logic package in handler.go when groups are using for api generation.

Thanks for your contribution, I checked the code generation of api again, it's unnecessary add an alias for group folder, for instance, there has an api file which contains part of content as following:

@server (
	group: test
)
service greet-api {
	@handler GreetHandler
	get /from/:name(Request) returns (Response)
}

the generated results' tree showing as following:

.
├── etc
│   └── greet-api.yaml
├── greet.api
├── greet.go
└── internal
    ├── config
    │   └── config.go
    ├── handler
    │   ├── routes.go
    │   └── test
    │       └── greethandler.go
    ├── logic
    │   └── test
    │       └── greetlogic.go
    ├── svc
    │   └── servicecontext.go
    └── types
        └── types.go

the handler's imports are

import (
	"net/http"

	"github.com/zeromicro/go-zero/rest/httpx"
	"go-zero-demo/greet/internal/logic/test"
	"go-zero-demo/greet/internal/svc"
	"go-zero-demo/greet/internal/types"
)

it works correctly. As your pr do, the imports should be

import (
	"net/http"

	"github.com/zeromicro/go-zero/rest/httpx"
	**logic** "go-zero-demo/greet/internal/logic/test"
	"go-zero-demo/greet/internal/svc"
	"go-zero-demo/greet/internal/types"
)

it's not a recommend solution.
