Deploying lower case boolean or string type in datamodel results in internal server error

[marktani]

Describe the bug
When you deploy a datamodel with a field of type boolean or string, you receive an internal server error, "No value found for 'boolean'" or "No value found for 'string'".

To Reproduce
Steps to reproduce the behavior:

1. Deploy this datamodel:

type Email {
  id: ID! @unique
  email: String
  default: boolean @default(value: false)
}

Note boolean, and not Boolean.

2. See error:

Creating stage dev for service lowercase-boolean ✔
Deploying service `lowercase-boolean` to stage `dev` to server `prisma-eu1` !

}

Expected behavior
deployment is interrupted, giving you an error message that boolean or string is not a valid type name. Did you mean Boolean or String?
