Fix contract init params

[MaxStalker]

Description

Contract init parameters can be defined on multiple lines like this:

init(
     a: Int,
     b: String
)

Previous implementation would fail to properly catch this. This PR adds changes to fix it.

i merged the flow-cli install fix but it looks like CI is still failing, mind checking this out then we can merge?

I will fix the issues now.

Do you know how I can fix inter-package importing in this lerna repo?
Tests are failing cause it can't find @onflow/flow-cadut module (for example)...
