fix(generators): replaces incompatible characters in schema with sane defaults

[akoenig]

This PR fixes problems with incompatible characters in the SDL. It replaces backticks with single quotes at the moment.

Background

I encountered today that the SDL contains annotated comments from time to time. For example:

"""
The `Long` scalar type represents non-fractional signed whole numeric values.
Long can represent values between -(2^63) and 2^63 - 1.
"""
scalar Long

This leads to a syntax error in ES2015 and TypeScript because the template string typedefs gets terminated by this data type annotation. This PR replaces backticks with single quotes:

"""
The 'Long' scalar type represents non-fractional signed whole numeric values.
Long can represent values between -(2^63) and 2^63 - 1.
"""
scalar Long
