Recode.Task.PipeChainStart (Recode v0.9.0)

Pipes should start with a raw value to improve readability.

# preferred
user
|> User.changeset(params)
|> Repo.insert()

# not preferred
User.changeset(user, params)
|> Repo.insert()

Starting a pipe chain with a function call instead of a raw value can make the code harder to follow, as the data flow is less clear.

This task rewrites the code when mix recode runs with autocorrect: true.
