Unable to deploy contracts having multiple-line `init` params

### Problem

when deploying contracts which have `init` params with `deployContract` or `deployContractByName`
it will throws `Error: Type Error: type is not a string` if the params are multiple-line like this:
```cadence
init(
   a: Int,
   b: Int
 )
```
but it still works with single-line params like this:
```cadence
init(a: Int, b: Int)
```
