Removed injectName helper

[radekmie]

As said in #717, there are different types of fields. A long time ago, a new injectName helper got introduced as NestField couldn't use context for context propagation due to the problems with blocking updates (more about it is in #716). This change simplifies NestField and removes the injectName helper completely.

This is a first step of removing includeInChain option of connectField. The only field that still uses it is the ListField, but it'd require one more change (more about it soon).
