Use `go mod tidy` before make (#799)

* Use `go mod tidy` before make 

I have the issue with go 1.16 that I cannot build dapr because of a lot of errors with the message:

```
missing go.sum entry for module providing package ...
```

Maybe it's because of this issue: https://github.com/golang/go/issues/44129

Executing `go mod tidy` fixed it for me.

* Update mod tidy check equal to the one used in dapr/dapr

 4. Register your component in dapr [main.go](https://github.com/dapr/dapr/blob/d17e9243b308e830649b0bf3af5f6e84fd543baf/cmd/daprd/main.go#L153-L226)(e.g. binding)

 6. Replace the installed daprd with the test binary (then dapr cli will use the test binary)
