Generate adapters based on type, not property

[Anatolii Afanasev]

@Kson
data class UserEntity(
    val firstname: String, 
    val lastname: String
)

// generated code
...
private val firstnameAdapter by lazy { gson.getAdapter(String::class.java) }  
private val lastnameAdapter by lazy { gson.getAdapter(String::class.java) }  
...

As you see, each property will have it's own adapter. I think better to have adapters grouped by types, f.ex:

private val stringAdapter by lazy { gson.getAdapter(String::class.java) } 

and use this adapter in both properties
